No, you can't recover from a SIGBUS (or other) this way. And it's
not safe to do so, even in interpreted mode.
You must not use any VM function (internal or not) inside a signal
handler, except lua_sethook() (but that doesn't help you here).
BTW: I consider posting a 600 line file from the distribution to
be an excessive waste of list bandwidth. Please don't do that again.
A small diff would have served the purpose just as well. Thank you
for your consideration!
