... I've been unable to reproduce the "!x123456" and its results, but it doesn't seem a stack overflow. It seems that you've just run out of memory, your shell has just tried to allocate some more 134 megabytes of memory, couldn't, and bailed. I would be more worried if you didn't get an error from the shell and just a SIGSEGV or SIGILL. Regards, Luciano Rocha
