The crash is occurring in Dovecot core code, not flatcurve.

You would need to do debugging steps listed at https://www.dovecot.org/bugreport-mail/ to gather sufficient information to confirm this is an issue with flatcurve, and to be able to determine what that issue is. Alternatively, you can provide a reproducible testcase that triggers the crash.
