I have serious doubts that this is the correct way to run tests, as
share ctors are supposed to have run BEFORE unit tests are allowed to.
It's quite possible (and likely) that unit tests are running before
critical other shared ctors have completed, which is why something
isn't working.
In any case, it looks like the unit tests have run, and run
successfully, and then main has run, and then it's the teardown of the
runtime that's hanging.
I'm not 100% certain, because I don't know exactly how this code comes
into play -- it's a string in this file.
Huh, shouldn't this problem have manifested itself earlier then? Why
only now? I don't remember this happening previously.
This is one of those very fragile and seemingly random types of things.
A change in code, a change in linker order, maybe even random chance,
can cause it to fail or not.
At the very least
I'm pretty sure I first encountered it last week. Unless something in
DMD was patched? But then there'd be no way I'm the only one
encountering this problem, and there don't appear to be any issues on
github's tracker.
It depends on what is actually hanging the process. If it's something in
your code base only, then nobody else would be seeing it.
