Parser - Segmentation fault when calling yytext

Question

My parser is recognizing the grammar and indicating the correct error line using yylineno. I want to print the symbol wich caused the error.

int yyerror(string s         


        

Answer 1

Are you using lex or flex? If you're using lex,yytext is a char[], not a char*.

EDIT If you aren't using flex you should be, it is superior in every way and has been from the moment of its appearance nearly 30 years ago. lex was obsoleted on that day.
