BTW, the emacs session from which I sent the bug report is of course not 
the one which crashed, but it has the same emacs version.

That value for b looks suspicious, but I don't know if we can get much
else out of this backtrace, unfortunately.

I think it wouldn't have given anything useful anyway, but for next
time, if xbacktrace is undefined, then you need to do

    source /path/to/emacs/src/.gdbinit

That was 42 weeks ago.  Have you seen this crash since?  Have you been
able to procure the output from xbacktrace requested above?  Thanks in

No, I could not reproduce this.

I am afraid we should close the bug.
