->Here is one simple code that reproduces this bug:

FYI: your test case also did have one bad typo:

-> pfGStateAttr(gset_state, PFSTATE_TEXTURE, tex);
-> pfGStateAttr(gset_state, PFSTATE_TEXTURE, tex_env);
                                ^^^^^^^^^^^^^^
                                should be PFSTATE_TEXENV

#include "Performer/pr.h"

                                { 1.0f, -1.0f, -5.0f },
                                { 1.0f, 1.0f, -5.0f },
                                {-1.0f, 1.0f, -5.0f } };
