Stack overflow or segmentation fault happens when working with large numbers in ‘type’ (threshold may vary depending on your system limits and on the command executed) Statement without assumptions Syntax error: [prim:reference] expected after 'Notation' (in [vernac:command]) Syntax error: [prim:reference] expected after [prim:reference] (in [vernac:command]) t Tactic failure Tactic failure (level ‘natural’) Tactic failure: succeeds Tactic failure: Setoid library not loaded Tactic generated a subgoal identical to the original goal Tactic Notation ‘qualid’ is deprecated since ‘string’. ‘string’ Tactic ‘qualid’ is deprecated since ‘string’. ‘string’ template and polymorphism not compatible Terms do not have convertible types The "at" syntax isn't available yet for the autorewrite tactic The & modifier may only occur once The 'abstract after' directive has no effect when the parsing function (‘qualid’) targets an option type The 'clear implicits' flag must be omitted if implicit annotations are given The 'default implicits' flag is incompatible with implicit annotations The / modifier may only occur once The command has not failed! The conclusion of ‘type’ is not valid; it must be built from ‘ident’ The constant ‘number’ is not a binary64 floating-point value. A closest value ‘number’ will be used and unambiguously printed ‘number’. [inexact-float,parsing] The constructor ‘ident’ expects ‘natural’ arguments The cumulative attribute can only be used in a polymorphic context The elimination predicate term should be of arity ‘natural’ (for non dependent case) or ‘natural’ (for dependent case) The field ‘ident’ is missing in ‘qualid’ The file ‘ident’.vo contains library ‘qualid’ and not library ‘qualid’ The recursive argument must be specified The reference is not unfoldable The reference X was not found in the current environment The reference ‘qualid’ was not found in the current environment The relation ‘ident’ is not a declared reflexive relation. Maybe you need to require the Coq.Classes.RelationClasses library The relation ‘ident’ is not a declared symmetric relation. Maybe you need to require the Coq.Classes.RelationClasses library The relation ‘ident’ is not a declared transitive relation. Maybe you need to require the Coq.Classes.RelationClasses library The term ‘term’ has type ‘type’ which should be Set, Prop or Type The term ‘term’ has type ‘type’ while it is expected to have type ‘type’' The type has no constructors The type ‘ident’ must be registered before this construction can be typechecked The variable ident is bound several times in pattern term The variable ‘ident’ is already defined The ‘natural’ th argument of ‘ident’ must be ‘ident’ in ‘type’ There is already an Ltac named ‘qualid’ There is no flag or option with this name: "‘setting_name’" There is no flag, option or table with this name: "‘setting_name’" There is no Ltac named ‘qualid’ There is no qualid-valued table with this name: "‘setting_name’" There is no string-valued table with this name: "‘setting_name’" There is nothing to end This command does not support this attribute This command is just asserting the names of arguments of ‘qualid’. If this is what you want, add ': assert' to silence the warning. If you want to clear implicit arguments, add ': clear implicits'. If you want to clear notation scopes, add ': clear scopes' This hint is not local but depends on a section variable. It will disappear when the section is closed This object does not support universe names This proof is focused, but cannot be unfocused this way This tactic has more than one success To avoid stack overflow, large numbers in ‘type’ are interpreted as applications of ‘qualid’ To rename arguments the 'rename' flag must be specified Trying to mask the absolute name ‘qualid’! Type of ‘ident’ is not an equality of recognized Σ types: expected one of sig sig2 sigT sigT2 sigT2 ex or ex2 but got ‘term’ Type of ‘qualid’ seems incompatible with the type of ‘qualid’. Expected type is: ‘type’ instead of ‘type’.

Give as argument to “Proof using” the list of section variables that are not needed to typecheck the statement but that are required by the proof ‘ ‘class’ must be a transparent constant ‘ident’ already exists ‘ident’ already exists. (Axiom) ‘ident’ already exists. (Definition) ‘ident’ already exists. (Theorem) ‘ident’ cannot be defined ‘ident’ cannot be defined because it is informative and ‘ident’ is not ‘ident’ cannot be defined because the projection ‘ident’ was not defined ‘ident’ is already declared as a typeclass ‘ident’ is already used ‘ident’ is both name of a Collection and Variable, Collection ‘ident’ takes precedence over Variable ‘ident’ is declared as a local axiom ‘ident’ is not a local definition ‘ident’ is not an equality of Σ types ‘ident’ is opaque ‘ident’ is used in conclusion ‘ident’ is used in hypothesis ‘ident’ ‘ident’ is used in the conclusion ‘ident’ is used in the hypothesis ‘ident’ ‘ident’ was already a defined Variable, the name ‘ident’ will refer to Collection when executing "Proof using" command ‘qualid’ cannot be used as a hint ‘qualid’ does not occur ‘qualid’ does not respect the uniform inheritance condition ‘qualid’ is already a coercion ‘qualid’ is bound to a notation that does not denote a reference ‘qualid’ is not a function ‘qualid’ is not a module ‘qualid’ is not an inductive type ‘qualid’ not a defined object ‘qualid’ not declared ‘qualid’ should go from Byte.byte or (list Byte.byte) to ‘type’ or (option ‘type’) ‘qualid’ should go from Number.int to ‘type’ or (option ‘type’). Instead of Number.int, the types Number.uint or Z or PrimInt63.pos_neg_int63 or PrimFloat.float or Number.number could be used (you may need to require BinNums or Number or PrimInt63 or PrimFloat first) ‘qualid’ should go from ‘type’ to Byte.byte or (option Byte.byte) or (list Byte.byte) or (option (list Byte.byte)) ‘qualid’ should go from ‘type’ to Number.int or (option Number.int). Instead of Number.int, the types Number.uint or Z or PrimInt63.pos_neg_int63 or Number.number could be used (you may need to require BinNums or Number or PrimInt63 first) ‘qualid’ was already mapped to ‘qualid’ and cannot be remapped to ‘qualid’ ‘string’ cannot be interpreted as a known notation in ‘ident’ entry. Make sure that symbols are surrounded by spaces and that holes are explicitly denoted by "_" ‘string’ cannot be interpreted as a known notation. Make sure that symbols are surrounded by spaces and that holes are explicitly denoted by "_" ‘type’ is not an inductive type ‘type’ was already mapped to ‘type’, mapping it also to ‘type’ might yield ill typed terms when using the notation
