Backtrace and immediate context for crash (DUSK)

The game DUSK (available on Steam) has a 64bit single player binary, and a
32bit multiplayer binary, both built in Unity.

The 32bit multiplayer binary works fine.
The 64bit single player binary (needed to play the bulk of the game - the
single player content) crashes on launch, with a backtrace suggesting a failure
to execute RtlAddFunctionTable (and RtlAddGrowableFunctionTable, which seems to
call it).

According to bug 46143, the Rtl family functions here are merely stubs, which
is probably why this doesn't work.

As the crash seems to happen within Mono, I would imagine this would break many
Unity, or Mono 2.0, based applications in 64bit mode.
