Something that's not clear to me when advised to add, should I be
uploading a v3 with your acked by? I think I got that wrong the last

It's not immediately clear to me either, but it's super later here...

Possibly, I think I already found one earlier tonight.

https://bugs.llvm.org/show_bug.cgi?id=32985

Tomorrow, I'll try to cut down a test case to see if this is indeed a

this just a simple clean up, in the meantime?
