Start with the Allocations instrument. It will show you the retain/release history of the dead object. (My guess is that the bug is the call to -getReturnValue:. That method simply copies the return value's bytes into the destination variable, but ARC thinks the destination variable stores a retained pointer. The Allocations instrument should show that the returned object is the one that is used after deallocation.) -- Greg Parker gpar...@apple.com Runtime Wrangler _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
