It happens if you try to do a GC operation while the GC is 
running.

The typical cause is allocating in a destructor. (Accessing 
reference type member variables from  class destructor is another 
way to get a crash, since the GC might collect them first.)


There's a handful of memory issues in D, some with the GC and 
some when you try to avoid the GC, but they typically don't 
bother me.... perhaps because I've learned to avoid problematic 
areas, like non-trivial class destructors.
