Hi,
I encounter the same bug using gcc 3.2.2, bison 1.75 and flex 2.5.4
I found that parser.c calls yylex without arguments, whereas lex.yy.c defines
yylex to be of type yylex(YYTYPE *yylval).
That means that bison does not build a pure parser, although YYPURE
was defined.
I do not know exactly whether it is gcc or bison that is behaving wrong,
but inserting the line :
%pure-parser
in the file parser.y.in (after the line: %start lines, for example)
was sufficient for me to solve this problem.
Regards,
Emmanuel
