That's a pretty confusing looking for loop construct. You can get the same behavior out of this: It freaks me out that you have IOIteratorNext() in that first arguent to the for loop. I don't know anything about how and when each of the 3 expressions in the for loop is executed behind the scenes in compiler-land, but what you're doing scares me :) hello all i've received a very weird crash report that i'm unable to track down cause the code in question works everwhere else and similar code is also in apple's sample code. the crash is happening in: "for(object = IOIteratorNext(iter); object != 0; object = IOIteratorNext(iter)) // iterate through all "IOATABlockStorageDriver"s" you can obtain the complete code in question here: http:// homepage.mac.com/julianmayer/SMARTReporterSource.zip and the complete crash log here: http://homepage.mac.com/ julianmayer/SMARTReporter.log and the system profile of the machine where the crash occurs here: http://homepage.mac.com/julianmayer/Profile.zip This email sent to ebold@apple.com This email sent to site_archiver@lists.apple.com
