Well, actually, no, I didn't miss it, but step 5 did not appear to
yield any additional information.  If I continue several times, I get:

I've tried instrumenting the code in dcrt0.cc to narrow down the
problem, without a lot of success.  The thread that is faulting out
here is the one created by sigproc_init().  But if I rearrange the
code in dll_crt0_1(), then instead, I get a similar fault in a thread
created by fhandler_tty_master::init().  So the problem seems to be
with a precondition for successfully creating a new thread.

What thread gets created earlier than the wait_sig thread?  I see that
gdb gives this thread id 3 but I can't tell what thread id 2 was; it
has exited (successfully?) before the trouble starts.
