At this point I'm pretty confident it's memory corruption of some kind.
Consider the following semi-STC:
1. Invoke: emacs-nox -Q; echo -e "att $(jobs -p)\nc" > /dev/clipboard; fg
2. ^Z
3. (switch to window running gdb and hit [shift]+[insert] to paste from
clipboard)
5. (switch to window running emacs): M-x compile C-a C-k ls [ret]
6. C-x o (to switch to the compilation output window)
7. Hit 'g' to keep repeating the "compilation" until gdb picks up a crash.
I tried a simpler version of this (without gdb and without
suspending/resuming):
1. Invoke 'emacs-nox -Q' in mintty.
2. M-x compile C-a C-k ls RET
3. C-x o
4. Hit 'g' repeatedly.
I got it to abort with Fatal error 6 after slightly over 100 repetitions.
I then tried the same thing with emacs-X11 (running under X, not in
mintty). I hit 'g' 200 times without a problem. I repeated this with
emacs-w32, again 200 times without a problem.
So there's a bug somewhere. But if it's an emacs bug, it's strange that
it only occurs with emacs-nox and not with either of the GUI versions of
emacs.
