I'm using tango trunk r4498, which is from right after 0.99.8, just when the stack tracing was added.
From a static ctor in WinStackTrace?.d, starting with line 1843:
SYMBOL_INFO sym;
extern(C) void function(char[]) initTrace;
if (SymFromName(GetCurrentProcess(), "__initLGPLHostExecutableDebugInfo", &sym)) {
initTrace = cast(typeof(initTrace))sym.Address;
//Stdout.formatln("Initializing the TangoTrace LGPL stuff");
initTrace(modName);
} else {
Stdout.formatln("Can't initialize the TangoTrace LGPL stuff");
}
From looking at it in the msvc debugger (unfortunately without symbols) it looks like the initTrace function pointer is null, causing an access violation when trying to call it.
Here's the corresponding assembly output, I've marked the spot with XXXX.

Let me know if you need more info, and I'll run it in the debugger again.
