Didn't get an email about your comment. Using the iPhone Simulator, I can catch "unrecognized selector" with "objc_exception_throw" and single-alloc/double-release issues with "malloc_error_break". However, I don't think you can breakpoint for single-alloc/single-release/message-to-released-object. The debugger indicates the last selector is "objc_msgSend", which you can indeed breakpoint, but it's used a lot normally. Sorry for the delayed response. Didn’t get an email about your comment.

Unfortunately, I haven't tried these breakpoints on 10.6, and a quick Google search didn't yield any helpful results. Sorry. I'd post the question to the cocoa-dev Apple mailing list. Hmm, strange.

I tried your suggested breakpoints, but am instead getting obj_error for both a single-alloc, double-release sequence, and a single-alloc, single-release, message-to-released-object sequence.
