ok, I'm pretty close. After debugging tcsh for more than three hours,
it looks like this is a kernel bug. I've traced it down to the following
code in sh.proc.c:
xprintf ("pp before sigpause %x\n",pp);
/* (void) sigpause(sigblock((sigmask_t) 0) &~ sigmask(SIGCHLD)); */
(void) sigpause(omask & ~sigmask(SIGCHLD));
xprintf ("pp after sigpause %x\n",pp);
pp gets clobbered by sigpause. I'll have a fast look at the kernel, maybe
it's easy to spot the bug.
See, you not only have to be a good coder to create a system like Linux,
you have to be a sneaky bastard too ;-)
