call stack tracing

[Mark J Twain via Digitalmars-d-learn]

Any solution out there that can get call stack, file and line 
info? Similar to exceptions but I simply want to track memory 
allocations and need the complete call stack rather than just the 
previous call(using __FUNCTION__/__FILE__/etc), which is usually 
useless.

Of course, exceptions have TraceInfo... could that be used 
anywhere or hacked to get what I need?
