Well, general heap corruption, I suppose, like overwriting the end of a block or writing to previously-freed memory. These kinds of problems are hard to track down. They're more likely to stem from C or C++ code than from Objective-C. You should try testing your app while running memory diagnostics like MallocScribble, Guard Edges and GuardMalloc.
