Sounds plausible :)

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...
