I modified druntime to support stack-tracing for all kind of exceptions.  
It's very simple:

1) In object_.d, change traceContext() function linkage to C:
extern(C) Throwable.TraceInfo traceContext(void* ptr = null) { ... }

2) In rt\deh.c, declare
Interface* traceContext(void* ptr);

and add the following line to _d_create_exception_object (rt\deh.c)
exc->info = traceContext(NULL);

that's it. Works like a charm!
