what is going on here?

[forkit via Digitalmars-d-learn]

strange things happen when I compile (on windows) the code below 
with:

dmd -m64
(compilation just crashes - no error message at all)
or

ldc2 -m64
(compilation works, but memory usage during compilation goes 
completely wild! upto 22GB, then down to 7GB, then finally 
completes.)
