Well, that line number has no code on it, so it's hard to tell exactly
where the PC value really lines.  Can you run gdb on your binary, do "info
line *PC" and "disas PC" and send me the output?  It looks like it must be
either a null pointer in thread->pcb (which would be some bad corruption),
or a null pointer as the PART argument.  You could insert printfs to see
what is up.
