Follow-up:The problem on DMD macOS is the "export" keyword. It ended up in my code during a similar-ish problem last year, when I was having trouble linking against DLL global variables on Windows.
If I remove the "export" keyword in the D interface, it will work on macOS but break on Windows. (To reiterate: WITHOUT "export" on Windows, it refuses to link. WITH "export" on Mac, it seems to link but with incorrect results)
Is this correct behavior?
