That shader object should always have a valid (i.e., non-NULL) instance
data pointer; if it doesn't then it's not a valid object.

I would look at the shader object in question, see if you can track its
instance data from when it's created until you hit this point.

When E3Shader_RegisterClass registers the texture shader class it asks
for sizeof(TQ3TextureObject) bytes of instance data.

When E3TextureShader_New allocates the object it should either get that
instance data or fail - so either it's failing at that point, or someone
tramples it later on.

Was GeomTest using the same version of Quesa (the Microspot flavour,
which did have some instance data changes) or the CVS version?
