Something about the personality routine is causing a SIGABRT.
Investigating further.
This occurs due to an assertion in _Unwind_SetGR. Seemingly, the
compiler intrinsic `__builtin_eh_return_data_regno` is doing something
it *really* should not. I'm not a compiler developer, and have no clue
how to investigate this.
This issue does not occur with Rust.
Additionally, LLVM's libc++abi manages not only to cleanly handle a Rust
panic, but also, through some voodoo magic that took me by surprise,
recognize Objective-C exceptions (and provide info on them) in its
terminate handler. Perhaps due to Objective-C++? Hell if I know.
Thought it was worth mentioning that other implementations *have* gotten
this working, though.
