[Windows & DMD] No callstack when crash with Access violation reading location 0x00000000

[Xavier Bigand]

I get some troubles to solve a memory bug, just cause I don't have any 
informations for debuggers and I can't neither use DrMemory.

Is it possible to get the callstack when calling a method on a null 
pointer with specifics DMD flags?

Maybe DMD need add null ptr call checks in debug mode?
