If the destination texture image doesn't exist we'd hit an assertion (or crash in a release build). The piglit/s3tc-errors test hits this. This has already been fixed in master by the error checking code consolidation. Note: This is a candidate for the 8.0 branch. --- src/mesa/main/teximage.c |

Just some quick comments. I think the term "GAMMA" should be omitted. I'm no expert but I'm not sure that sRGB is strictly a gamma function. The GL_EXT_texture_sRGB spec says "The sRGB color space roughly corresponds to 2.2 gamma correction." Also, the term GAMMA doesn't appear in any of th
