No success to report in getting that, but GDB ate all my 16G of memory in the
middle of work day in trying to get the backtrace, and was still busy:

#v+

Mem: 11G Active, 1242M Inact, 2730M Wired, 501M Cache, 2268K Free

I'll run the emacs build under resource limits, and hopefully get you a
useful stacktrace tomorrow.
