I have a case when Transcode to PVRTC4 crashes reproducible while compressing the image.

Hi Andreas, Would it be possible to get a copy of the image? You can either post the image to the forum or send it to [devtech@imgtec.com](mailto:devtech@imgtec.com) and I’ll be happy to take a look at what’s going on 🙂 Thanks, Tobias ---

Hmm, that should be fine, it might just take a while to get here I guess! I’ll take a look once it’s arrived. Thanks! ---

It looks like it's a compressor bug, rather than any of the intermediate code - so I'm just waiting on the pvrtc team to give me a fresh drop of the compressor. I'm not sure yet what it is about this particular image that causes the crash. I'll let you know whether the new code fixes the issue or not when i've got it integrated - but this is likely to take a few days at this point. Tobias2012-04-02 09:27:02 ---

Hi Andreas, There’s a new version of PVRTexTool available on the website now which fixes this issue. Sorry it took so long! Let me know if you have any further problems. Thanks, Tobias
