I've no idea how it is used but '_d_traceContext' might be of use:

import std.stdio;

int foo(int n)
{
	writefln("&foo: 0x%X", &foo);
	writefln("%s", _d_traceContext(&foo));

	return n;
}

extern(C) Throwable.TraceInfo _d_traceContext(void* ptr = null);

void main(string[] args)
{
	auto x = foo(100);
}
