Hello,I've written a bison based parser, where I defined YYSTYPE as pointer to a C structure, which I am allocate within lex/flex and free within bison. This seems to work fine if no parser error occurs. But if an error occurs and the parser unwinds its stack, I have no chance to free them.
What is the recommended strategy in such situations? Regards, Oliver Fischer
