This RC3 version of 1.20 First Look crashes this particular laptop every time I try to start the program. Note that RC1, RC2 and the current 1.19.x release versions all work fine with this laptop.
Initialization is successful through the "Loading World..." phase, but as soon as the world and my avatar appear, the program instantly crashes to the crash logger. This is NOT an nVidia card, so it's not that graphics-driver problem (and in fact, a different laptop with nVidia graphics worked fine with this RC3 rendering the same scene.)
Looking at the logs, I see that the failure seems to be marked with an ASSERT from the code, and here it is:
ERROR: ASSERT (raw_image->getDataSize() >= sculpt_height * sculpt_width * sculpt_components)
So I'm going to cross -link this with VWR-2404 on the chance that it's related to the new-but-not-quite-working fix to the handling of lossless sculpty textures. Since THAT bug was related to pulling lossless maps from the cache, I'll report back as to whether clearing cache on startup makes the problem go away.
Also posting a zipfile containing the salient crash logging information.
