Hi groups,

I have a problem using flex to parse a file.

The following rules has been defined:

{space}{alnum}        {
  yylval.string=(char*)strdup(yytext);
  return(ALNUM);
}

But as described in the strdup manual, a memory allocation is done. I
have a leak and I would like to know where to put the free memory
allocation:in the flex code or in the bison code ?

I'm not expert in flex&bison, I need a good help.
