What else would help? strace?
Do you have the opportunity to build Dovecot yourself, thereby including the debug symbols?

Hi Stephan,
I managed to get GDB, I hope this one helps. If not I can send the config too, but exactly same config works with 2.3.6.
You don't have the debug symbols for Dovecot installed. Usually, your system will have a separate package for that. On Debian, it is called dovecot-dbg.

Hi,
If we use sieve redirect under dovecot 2.3.7.2 we end up with

Sorry, not knowledgeable enough on how to do the GBD debug.
We went back to previous version and issue disappeared.

Anyone else already had this problem or you know how to fix it?
I can't readily reproduce it with the information available so far. Do you have the opportunity to obtain a GDB backtrace? You can e.g. run LDA manually at the command line with the same arguments and message input Postfix provides and wrap it in GDB if you can reproduce the crash.
Your configuration may also help (output from
dovecot -n)Regards,
Stephan.
