want to send us your testcase code? Then we can give it a whirl.

...in a third file that simply does "throw 1;" compiled
with g++-llvm
- I can definitely see the personality function in the exception headers and
it's definitely not being called.
- If i replace "throw 1" with "result = _Unwind_RaiseException" then result
is 5 - i.e. END_OF_STACK.

[LLVMdev] Exception handling question
Yes. The issue here, as you pointed out, is that your personality function is not called at all.
Even if you did nothing in the personality function, associated with the setup caused by
llvm.eh.selector, but returned _URC_CONTINUE_UNWIND (8), it should still be called.
Your results are acting like either dwarf exception header info is not emitted (llvm::DwarfExceptionHandling = true;
not executed
