To work towards a fix will however need better info. A first cut would be just a "-ggdb -O0" build, and inspect the stacktrace for obvious null-pointers in function args.
We created a build with the mentioned flags. But with this version, no segfaults are directly reported and no core file created.
Instead the following is shown: LOG: MAIN PANIC DIE bad memory allocation requested (-83643 bytes) at string_localpart_utf8_to_alabel 146 LOG: MAIN PANIC Delivery status for ������@somehost.net: got 0 of 7 bytes (pipeheader) from transport process 108 for transport smtp Compared to: LOG: MAIN PANIC SIGSEGV (maybe attempt to write to immutable memory) LOG: MAIN PANIC Delivery status for ������@somehost.net: got 0 of 7 bytes (pipeheader) from transport process 92288 for transport smtp I guess that's no big help. If desired, I can provide the spool files causing the segfaults.
