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

[Benjamin Thaut]

Ok, I can reproduce this, and it seems that the crash happens somewhere 
in no mans land. That means there is no debugging information present 
and the stack frame isn't valid either. So the debugger and druntimes 
buildin stacktrace code has no chance. My guess would be that this 
happens inside druntime or phobos. So to debug this issue you will have 
to build a debug version of druntime and phobos (just modify the DFLAGS 
variable inside the .mak files accordingly and build them using the 
digital mars make). And then link against these debug versions (using 
the -debuglib switch). I would recommend renaming the debug versions so 
you can use them whenever needed. I will take a deeper look tomorrow.

Kind Regards
