...out the terminate and resume calls for the time being, I see my personality function being called twice -- first for the C++ exception (Exception code == 0xe06d7363) and once for the unwind.

Thanks for the additional information. Right now I’m experimenting with a mix of code compiled with MSVC and code compiled with clang, trying to get a C++ exception thrown and caught by the MSVC-compiled code across a function in the clang-compiled code. My goal here is to isolate a small part of what needs to be done in a way that lends itself to tinkering. I think this might lead me to the
