Maybe.  The abort was due to a bug in the GTK+ tool bar code, which I
reported and Jan D. quickly fixed.  I suppose it is possible that
do_auto_save was being executed when the abort occurred, is it?  When
the initial abort occurred, resulting in the erroneous auto-save-list
file, Emacs was not running under gdb, but, as I wrote in my bug report
about the abort, even reproducing it under gdb yielded no backtrace, why
I don't know.  (The abort locked up my desktop and I could unlock it
only by killing the emacs process, after which, when I tried to get a
backtrace, gdb just said "Cannot access memory at address 0x8321b6c".)
