Ok, do the following.  Start your bhyve command under gdb. Like this:
/usr/local/bin/gdb /usr/sbin/bhyve
(gdb) set args ...
(gdb) run
Now on assert the process should stop in debugger instead of terminating,
and hopefully bhyvectl would find still alive VM.

What exactly is the 'failure' ?  Is it SIGSEGV, other signal,
error returned from ioctl, etc ?
