How do I trace that memory error?

[Marc via Digitalmars-d-learn]

I've tried both gdb and windbg debugger both it either get a 
"received signal ?" from gdb or crash the GUI application 
(windbg).
The error is:

core.exception.OutOfMemoryError@src\core\exception.d(696): 
Memory allocation failed

How do I find out the source of the error?
