Antlr3 C++ code generation hangs

[Sebastien Van Cauwenberghe]

Hi All,

I'm generating a parser in C++ and I don't understand why with this grammar,
Antlr gets stuck... It can run for 20 min 100% cpu without generating
anything.

Has someone an idea ?

Thanks in advance for your support
Cheers

Sébastien

Are you using the multithreaded option?
ANTLR sometimes hungs when is it set on. Try to omit it.
