TestMipMaps() function in src/OGLconform/textureNPOT.c calls glTexImage2D() with width = 0. Texture with zero image width skips miptree allocation due to a condition in function _mesa_store_teximage3d(). While calling glGetTexImage() it results in assertion failure in intel_map_texture_image() due to null mt pointer
