IIRC I'm only able to reproduce this for aarch64 (and possibly arm) targets 
unfortunately. I can make a kind of standalone testcase with one single file 
built from source, linked and executed along with a bigger piece of code 
(either from source or prebuilt object files), but it'd be for aarch64-linux 
(or aarch64-darwin if that helps - I haven't tried reproducing it there but I'd 
presume it behaves the same as I noticed the bug first on aarch64 windows).
