  Ahh, I didn't realize you were intentionally trying to use the 
exception for the error output.

  I wonder, this sounds like a TLS (Thread Local Storage) issue 
where the local thread's stderr was updated but the global 
(shared?) one wasn't.

https://dlang.org/phobos/std_stdio.html#.stderr

The stderr is defined as "File stderr", not shared. I'm convinced 
TLS is the likely culprit. Unless you can affect the original 
instantiation it probably isn't going to work. I just tried using 
a static this() and it has a similar effect but doesn't affect 
stderr. :(
