rawlog files are plain text, readable files. you do not need to dump

can you get gdb "bt full" for the core file?

Hello everybody,
i tried to debug imap sessions with the rawlog feature and rawlog
creates files but when i try to dump them doveadm tells me
[...] Error: zlib.read((file)): unexpected EOF at [...].
I looked at syslog files and i see, that rawlog gets
terminated with a segfault, e.g.:
segfault at 10 ip 00007ff6da362596 sp 00007fffe725a080 error 4 in
libdovecot.so.0.0.0[7ff6da2a4000+122000]
Is there a way to debug why rawlog ist terminated? I haven't found
anything.I would be very thankful, if somebody could give a hint.
My system is:
