My iPhone app is crashing for certain users in UK. I tried using UK timezone and their region format but couldn't reproduce the crash on my iPhone or emulator. Eventually got a crash report and I was able to symbolicate it. However, I have a hard time understanding the results. It appears thread 0 crashed in a system library. The only call from my app is main.m.
Thread 4 has something familiar. It was at:
My App 0x00004cca -[TocTableController parser:didEndElement:namespaceURI:qualifiedName:] (TocTableController.m:1369)
Code is:
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
It crashed doing alloc/init? Out of memory, only in UK? Any one has idea what might be cause? Thanks in advance!
