Hi,
The stack size was the default 8192 kB. I have -- reluctantly, but in
the interest of debugging -- set it to 65532 kB via ulimit and then
launched emacs from that shell.
How can I verify from within Emacs what stack size it is running with?
I will keep it like this for a couple of days and see if I get more
crashes. If I do, I will report and move on and upgrade to HEAD.
