Possible hack to workarround the problem.

The app seems to pass an empty byte code as shader into
D3DXGetShaderConstantTable(). Thus it's not D3DSIO_END and will read through
the whole address space which will more or less crash sooner or later if no
D3DSIO_END is hit by luck.

There are two issues:
- Tests show that D3DXFindShaderComment() (which is used by
D3DXGetShaderConstantTable()) returns 0x88760b59 if it gets an empty byte code.
- D3DXGetShaderConstantTable() returns D3D_OK aclearednd table = NULL

Please try the attached patch (on clean git).
