[antlr-interest] Re: urgent problem with stack overflow, please help

[netminka]

Thanks for your reply.
I don't believe I could have recursion as a problem because
the parser stack trace does not show that. I can get files of
very large size through the translator, the only problem is with
individual procedures, their size over a certain limit causes
stack overflow. If I split them into smaller procedures,
otherwise same code, no problem.
