I experienced problems with gcc3 as well, 3.3 at least, under some circumstances. I suspect this very much depends on what values the compiler decides to put on the stack, which depends on your CFLAGS. Speaking of which, a -g compile on PPC uses quite a lot of stack -- I had to up the default limit in order to get anything to work (for example, compiling psyntax). That would be another issue though...
