Sometimes I have to wait 4 hours, sometimes it's the next time I do it. It is the complete backtrace, yes. It could very well be. I normally type q s immediately after another when leaving the summary mode. Yes, I ran on the same machine (a laptop) 21.1.4. I installed 21.1.6 just to see this bug fixed. On my desktop machine I have 21.1.2 but here I don't use Gnus. Sorry, cannot asnwer this. Anyhow, I have now a version with all debug info compiled in and will try to get more information. -- ---------------. drepper at gnu.org ,-. 1325 Chesapeake Terrace Ulrich Drepper \ ,-------------------' \ Sunnyvale, CA 94089 USA Cygnus Solutions `--' drepper at cygnus.com `------------------------
