Running 0.9.0 on Ubuntu 7.04 host, a Ubuntu 7.04 guest crashes when I
dereference -1. This also happens on a Windows XP host running the
precompiled Qemu 0.9.1. Both with kqemu.
#include <stdio.h>
main()
{
int *foo = -1;
printf("hello, world %d\n", *foo);
}
-kb

I suspect SIGSEGV isn't handled correctly or just passed to the host,
thus triggering process termination.
