If you are on linux and add this file to your project:
dmd2/src/druntime/import/etc/linux/memoryerror.d

(it is part of the regular dmd zip)

you might have to import it and call registerMemoryErrorHandler() 
but then it will do the magic tricks to turn a segfault into a D 
exception.

But this is a bit unreliable so it isn't in any default build.
