Hi,
dovecot (and no other program I use on this machine... at least not that I
notice it) segfaults in ld-elf.so.1 after an update from 2024-01-18-092730
to 2024-02-10-144617 (and now 2024-02-11-212006 in the hope the issue would
have been fixed by changes to libc/libsys since 2024-02-10-144617). The
issue shows up when I try to do an IMAP login. A successful authentication
starts the imap process which immediately segfaults.
I didn't recompile dovecot for the initial update, but I did now to rule
out a regression in this area (and to get access via imap do my normal mail
account).
Backtrace:
