I thought so too, and the fact that running the app from Instruments has no problems at all made me wonder what was going on. So I isolated the problem to to what I showed here. Displaying, writing or printing crashes the same way unless running under Instruments, then it all works. Does instruments do something when running that would "fix" an invalid reference? I run in XCode both with and without zombiew hunting mode and nothing shows in Instruments, which I've used to trap several other results of GC -> ARC failures. / Totte > > On Jan 17, 2014, at 4:22 AM, Totte Alm <to...@code66.se> wrote: > >> Hello again, >> >> Still debugging my CG -> ARC move and I'm stuck with one problem that I just >> can't understand. >> >> DEBUG SNIP WHERE THIS HAPPENS >> _thePDF = [[PDFDocument alloc] initWithData:_data]; >> // test- >> if (_thePDF) { >> @try { >> *CRASHES HERE* -> [_thePDF writeToFile:[NSString >> stringWithFormat:@"%@/PDFtemp-%f-h.pdf", NSTemporaryDirectory(), [[NSDate >> date] timeIntervalSince1970]]]; >> } >> @catch (NSException *exception) { >> NSLog(@"Ex:%@", [exception description]); >> } >> @finally { >> // None >> ; >> } >> } >> // - test >> >> This code crashes with the dump below, but only when running from XCode.
