Maybe, I don't know. FWIW, this is the first time I see temacs crash
like that.

I cannot figure out how; suggestions welcome.
The problem is that valgrind doesn't really run the machine
instructions from temacs on the real CPU. Instead, it runs a modified
instrcution stream (modifications are its instrumentation of the code)
on a synthetic CPU provided by the valgrind core. Given this, I can't
seem to find a way to run "valgrind ./temacs" under GDB, and without
that, how can I debug this?

Most probably, although on GNU/Linux we use the one from glibc, IIRC
(which is Doug Lea's variant).
