ios - iPhone app crashes on some devices upon startup, but runs on others -
we migrated ios 6 app ios 7 without altering in particular beyond minor adjustments. tested app on 3, 4, 4s , 5s iphones , reported no problem.
now 2 users reporting app crashes upon startup. advised 1 of them remove app altogether , install again resulted in app running smoothly.
he forwarded crash log me it's little cryptic. can me pinpoint issue?

i venture guess update included 64 bit update ios7 + iphone5 , data might formatted incorrect formatter:
ie: [nsstring stringwithformat:@"some foo %d"];
this might work 32 bit int fail on 64 bit platform.
are there warnings when compile binary?
