That number is 0x7FFFFFFFFFFFFFFF, which is particularly recognizable and happens to be the value of NSNotFound. I imagine that in the preceding line of code you called -indexOfObject: on an array that didn't contain the object, but then failed to test the value against NSNotFound before trying to fetch from that index. > More precisely, is there a way I can determine the location in the code where > the exception occurred? Do you have symbols for the particular build of the app that crashed? If so, there ought to be some way to symbolicate the list of addresses in the "Stack trace:" line of the log messages... although maybe not, without knowing the base load address of the executable. A full-on crash report, rather than log messages, would be a lot more useful. -ben _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
