Perhaps tangential to the discussion, but longjmp / setjmp has bitten

and stack unwinding isn't a thing -- it's these.

IIRC, you can compile Lua as C++, in which case it won't use setjmp / longjmp but do The C++ Thing, and then all of that should Just Work.

(If you look at the top of `ldo.c`, all the ugly stuff is tucked away in a bunch of small macros and should be relatively easy to change, if an alternate exception mechanism is available.)

(@Soni: Have you tried messing with that or do you already know that this doesn't help with the Rust situation?)
