gdb backtrace would be helpful in fixing the crash. http://dovecot.org/bugreport.html

Probably you can do simply:

gdb --args /opt/dovecot/bin/doveadm -Dv force-resync -u cory INBOX
run
bt full

or if that doesn't work (or simply gives "??" lines or other unusable garbage), try:

ulimit -c unlimited
/opt/dovecot/bin/doveadm -Dv force-resync -u cory INBOX
gdb /opt/dovecot/bin/doveadm core
bt full

Also the just released v2.1.11 fixes some potential crashes.
