Subject: | Bug repor for bison |
Date: | Sat, 11 Nov 2000 00:34:12 -0800 |
Hello,
We just figured that there is a bug with YYPRINT
and YYDEBUG. We defined YYDEBUG which bison also defined in side on C code.
After that we checked it once again check for yydebug value which has not been
initialized to 1. Condition fails on linux - bison version 1.28 because it may
take random value when you define it.
YYPRINT is not documented. Moreover we saw lines
like follows in bison generated code.
#ifdef YYPRINT
YYPRINT(stderr,
yychar, yylval);
#endif
Could you please explain what it does.
Thank you.
