Hi, Hopefully any of you have either a clue about bison or an idea how to solve this problem.
What happens now is that during parsing memory is allocated. If everything is parsed there is a set of malloc'ed memory all pointing to each other, etc. The main problem is in case of a syntax error. In that case all of the state should be released (free all memory structures). But I have no idea how to do that; yyparse just returns an error. I need a way to make bison return a valid structure so I can check if parsing failed and release all of the memory. One solution to this problem is making a big list of all memory allocated while scanning and parsing. When parsing fails you just free all of this memory. Otherwise everything is freed when the datastructures are about to be de-allocated. But I prefer a solution using bison stuff, otherwise I'll just use the solution I described above. -- Marco _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
