Hmm. Continuing, and then mucking about a bit, and I'm back in DDB.

  I think I missed a stack frame because I hit trace too soon...

  Now signal b = 13 = SIGPIPE, which is not the signal I want, I
think. So I continue, looking for something like SIGILL or SIGSEGV to
pop up, and then try and figure stuff out?
