>Description:
I installed fresh mail/cyrus-imapd23 port and tried to run
`cyradm' (a perl script delivered by Cyrus).
This causes perl-executable to dump core. Debugger gives the
following stack:
0x28250c65 in free () from /lib/libc.so.7
(gdb) where
#0 0x28250c65 in free () from /lib/libc.so.7

#12 0x08048938 in main ()
Note, that the machine does not have Kerberos configured.
The problem may be with the sasl2/libgssapiv2.so.2 doing
something stupid, but our GSS-API should, probably, be
smarter than freeing something unallocated (a NULL?)
>How-To-Repeat:
>Fix:
Remove (or bzip2) the Cyrus-installed sasl2/libgssapiv2.so.2 so
as to exclude from the list of candidates for client-server
authentication.
