Description Raimar Sandner 2008-01-14 00:28:26 UTC
gpg-agent sometimes crashes after the second query. 

Reproducible: Sometimes

Steps to Reproduce:
1. eval `gpg-agent --daemon`
2. gpg --no-options --use-agent --no-tty --sign --local-user 59426429 -o /dev/null /dev/null
3. enter pin
4. gpg --no-options --use-agent --no-tty --sign --local-user 59426429 -o /dev/null /dev/null

Actual Results:  
Sometimes gpg-agent processes the second query, but crashes. On other occasions, the agent just works. This is maybe related to #204662.

Expected Results:  
gpg-agent should continue running

gnupg is compiled with CFLAGS="-g -ggdb".

backtrace

don't know if this helps...
Comment 7 Alon Bar-Lev (RETIRED) gentoo-dev 2008-01-14 14:29:43 UTC
Yes it helps.

But I cannot reproduce this!!!!
I upgraded to glibc-2.7 and still all work correctly.

Can you please sync portage, I added debug USE flag to pth, set it and reemerge pth and gnupg.

Run it this way:
gpg-agent --daemon bash
$ echo ${GPG_AGENT_INFO}

At a second shell you should rest GPG_AGENT:
$ export GPG_AGENT_INFO=<whatever>
And the do your stuff...
I hope the debug log of pth will be helpful.

Thanks!
Comment 8 Raimar Sandner 2008-01-14 15:58:09 UTC
I have a hard time reproducing the bug myself. Well, maybe the solution is to re-emerge first pth and then gnupg...

Will do some more testing, feel free to close the bug for now.

Thanks for the help.
Comment 9 Alon Bar-Lev (RETIRED) gentoo-dev 2008-01-14 17:28:51 UTC
Can you reproduce this every time on gnupg-2.0.8?
Comment 10 Raimar Sandner 2008-01-14 23:54:02 UTC
Negative, gnupg-2.0.8 and gnupg-2.0.7 gpg-agents work as expected at the moment. But pth debugging messages are still shown, even after recompiling pth without debug USE-flag.
Comment 11 Raimar Sandner 2008-01-15 00:07:53 UTC
Ok, just synced, and with pth-2.0.7-r1 everything is back to normal, no debugging messages anymore and working gpg-agent.
Comment 12 Alon Bar-Lev (RETIRED) gentoo-dev 2008-02-13 12:59:32 UTC
As per comment#7, I cannot reproduce this.
If you have a valid scenario, please post and reopen.
Thanks!
