Debugging symbols were stripped. Could you try building it without
removing them, at least from dovecot-auth binary? I guess "make install"
does the stripping, so maybe copying the file manually would preserve
it. You can anyway check this with "file dovecot-auth" to see if it says
"stripped" or "not stripped".

Also this backtrace is corrupted for some reason. One (pretty) sure way
to get a non-corrupted backtrace is to attach gdb to dovecot-auth while
it's still running:

gdb attach <pid of dovecot-auth -w process>
cont
<wait for crash>
bt full
