Thanks for the detailed log! It shows what I thought might be happening -- the number of cache slots being zero for the type of slot chosen: XAAInitPixmapCache; FreePixmapCachePrivate Num256++; 1 Num256++; 2 Num256++; 3 Num256--; 2 Num256--; 1 Num256--; 0 XAACacheTile() [1] *current: 0; max: 0; pCache: 0; w: c8; h: c8; size: c8 [2] *current: 1; max: 0; pCache: 0 Since it is possible for zero slots of a particular type to be available, the XAACache* functions need to be able to handle this. Returning the NULL value in that case, and checking for it looks reasonable to me, but Mark might have a better idea. Whatever the best solution is, it looks like it will need to be applied to other places too. David -- David Dawes Founder/committer/developer The XFree86 Project www.XFree86.org/~dawes
