Hi all,

It happens at strange times, invariably during I/O of some kind (either
keyboard input or output from some compilation window); I don't get the
impression it's fork-related. I don't know how to get a backtrace from
emacs, given the way any exception or signal always loses the "userland"
stack (suggestions welcome).
Anyone else seeing this?
This doesn't really answer your question since I don't use emacs-nox,
but I've been running 64-bit emacs-X11 and finding it very stable. I
typically keep it running for several days at a time.
You say you don't know how to get a backtrace from emacs. I assume
you've installed emacs-debuginfo and run emacs under gdb. Are you
saying you can never get a backtrace after it crashes?
