Good news: I got a core file from a segfault. Bad news: I'm using a

I suppose that in order to get a useful backtrace, I have to compile
my own
dovecot, or at least dovecot-auth, with debugging symbols?
..
#2 0x00007f06ac1f854f in calloc () from /lib/libc.so.6
The crash is in memory allocation, which means something had corrupted
memory already. The only way to really solve this would be to run
dovecot-auth via valgrind:
auth_executable = /usr/bin/valgrind /usr/lib/dovecot/imap/dovecot-auth
That slows things down of course.. What PAM plugins are you using?
Those would be my first guess as to what's broken.
