I get some random crashes which I'm not able to isolate or reproduce easily. But it crashes every now and then, assumably when x/y scale of active objects is being adjusted under certain conditions. There are following EXC_BAD_ACCESS errors in Xcode (in Thread 1, there are also some others).
MMF build 256.31
Xcode 4.6
iPad 1, iOS 5.1.1
Does this say something to you, what could cause this type of crash?
CRenderer.m:
//Remove one unused texture at a time.-(void)pruneTexture
{
int index = [texturesToRemovesize]-1;
if(index >= 0)
{
ITexture* texture = (ITexture*)[texturesToRemoveget:index];
//Recheck that the texture wasn't used
if([texture getUsageCount] == 0) EXC_BAD_ACCESS
[selfremoveTexture:texture andCleanMemory:YES];
[texturesToRemoveremoveIndex:index];
//NSLog(@"Pruned texture %@", texture);
}
}
