Gnus + auto-compression-mode => SIGABRT

[Stephen Berman]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


I have gotten a SIGABRT by trying to open gzipped tar files from dired
with auto-compression-mode enabled; as far as I can tell, this only
happens after I have started Gnus (No Gnus v0.2, CVS from 2004-03-10,
but I think this also happened with Gnus 5.10.6).  I haven't been able
to reliably reproduce this, but it has happened repeatedly under my
personal Emacs configuration and at least once with -q --no-site-file.
Below is a gdb session (it's from the -q --no-site-file abort, but the
aborts under my personal configuration yielded the same backtrace).

Program received signal SIGABRT, Aborted.
