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

Hi Reid, I saw your patch but haven’t looked closely at it yet. I do have a work in progress for the outlining. I expect to have something ready to share pretty soon, hopefully by the end of the week.
