Under Windows, access violations cause the OS to throw an exception.
Since D uses the same EH mechanism as the OS, this integrates nicely.

Under linux, SIGSEGV is a signal, and you can't safely throw exceptions
from signal handlers, so D just aborts.

As far as I understand it, it's a limitation of the way linux is designed.
