Description Roland "Test-tools" Bär 2007-08-06 06:57:55 UTC

In the "not found" case in previous, the index is at 8, overrunning the buffer by one. Added check, please apply attached patch.

Comment 2 Michel Dänzer 2007-08-06 07:23:51 UTC

This should already get caught in *CheckCompositeTexture. Doesn't it?

Comment 3 Roland "Test-tools" Bär 2007-08-07 00:18:45 UTC

Ok, if it somehow guaranteed, that previously it has to go through R[12]00CheckCompositeTexture(), then this is a "can't happen".
