trying setjmp or throwing from signal handler crashes on OSX

[timotheecour]

Is there any way to get setjmp to work in a D program on OSX?
I just get a segfault whenever it is called.

I'm just trying to recover from a signal handler.

Related questions:
why is signal handler nothrow?

I saw this related thread but it seems linux only:
