OK, I tried that revision with the same problem.
I don't really know what I'm doing, but one odd thing I noticed while
playing around with Paul's suggestion to set a breakpoint on
delete_process:
1. Set a breakpoint on process.c:808. Print p.pid and do a xbacktrace.
2. Run gnus.
3. Gnus uses imap.el to get mail from my host.
4. Imap.el calls delete-process from imap-close
$1 = 1356
"delete-process" (0x88bf48)
"imap-close" (0x88c248)
"mail-source-fetch-imap" (0x88c584)
5. Imap.el calls delete-process to delete the same pid from
imap-sentinel
$2 = 1356
"delete-process" (0x88b928)
"imap-sentinel" (0x88bc24)
"delete-process" (0x88bf48)
"imap-close" (0x88c248)
"mail-source-fetch-imap" (0x88c584)
6. Let gnus sit for about a minute. The error is signalled with the
same pid
