Hello,

I'm experiencing a segfault, so I've followed the steps at http://www.dovecot.org/bugreport.html in an effort to capture the information necessary to submit a bug report.

Full "doveconf -n" output is at the end of this message.

Dovecot does seem to dump a core file, but when I attempt to parse it, I get this:

# apt install dovecot-dbg lib64stdc++6-4.9-dbg # gdb /usr/lib/dovecot/deliver /var/vmail/tmp/core-deliver-6-5000-5000-29125-1473732949 # Generic gdb GNU disclaimers and such here... Reading symbols from /usr/lib/dovecot/deliver...Reading symbols from /usr/lib/debug/.build-id/49/c9c607c304a5c853c05a4ccb9e4b995f185ac4.debug...done. done.

warning: core file may not match specified executable file. [New LWP 29125]

warning: the debug information found in "/lib64/ld-2.23.so" does not match "/lib64/ld-linux-x86-64.so.2" (CRC mismatch).

Core was generated by `/usr/lib/dovecot/deliver -d sa-training@example.com -m Training.HAM -p'. Program terminated with signal SIGABRT, Aborted. #0 0x00007f7712e77418 in __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:54 54 ../sysdeps/unix/sysv/linux/raise.c: No such file or directory. (gdb)

The obvious question is why the "core file may not match specified executable file".

What am I doing wrong here?

Any help would be greatly appreciated.

Thanks in advance!
