Looks like it is pretty easy to do. Check out

dmd2/src/druntime/src/rt/deh.d

The Access Violation error is thrown on about
line 635. There's a big switch that handles a bunch
of errors.

Yeah, Linux does it as a signal which someone has
tried to turn into an exception before, which kinda
works but is easy to break. (I don't remember
exactly why it didn't work right, but there
were problems.)
