--- Comment #1 from Alistair Leslie-Hughes  ---
Unlikely this commit would of caused the error.

Firstly, set d3dcompiler to native.  (without it you wont get far).

Once using native d3dcompiler, the crash is caused by missing support in
D3DXComputeTangentFrameEx for binormal vectors.

Last lines of a +d3dx log.
