"Well then don't call it with a ludicrous value of say 20000. I don't
know."

OK, Tony Hancock returns you to your scheduled response:

If calloc has a significant crisis and fails with a bus error or
something, this would explain a hang like this. Does the Yaroze
provide the ability to install an exception handler? I'd expect it
wouldn't, but it's worth a shot.

If this is the one declared in malloc.h, incidentally, then this isn't
the GNU calloc, but the Sony library implementation. (No way would
this explain its poor fault tolerance ;=)
