Got a EXC_CORPSE_NOTIFY symbol crash, how to track it?

Question

Here\'s the whole crash log. What\'s the meaning of EXC_CORPSE_NOTIFY exception notice?

I have to replace some strings about our company.

Answer 1

EXC_CORPSE_NOTIFY is irrelevant. The important information is in the Exception Type (EXC_CRASH (SIGABRT)) and the backtrace.

0   CoreFoundation                  0x1840c5900 __exceptionPreprocess + 124
1   libobjc.A.dylib                 0x183733f80 objc_exception_throw + 56
2   CoreFoundation                  0x183faf134 -[__NSArrayM insertObject:atIndex:] + 808
3   XxxxxXxxApp                     0x100a5e830 -[LotumMobStatLogManager createLogHeader] + 1616

A crash in -[__NSArrayM insertObject:atIndex:] usually occurs when you are attempting to insert a nil object into an NSMutableArray. I'm not sure what LotumMobStatLogManager is, as you haven't provided the relevant source code. If that is an external dependency, I would reach out to the developers with this crashlog and tell them that their createLogHeader method is doing something to cause an exception, possibly attempting to insert a nil object into an NSMutableArray as I mentioned above.

Answer 2

There are 2 possible reasons:

1, You are trying to insert nil into that array.

2, You are trying to insert to an index which is beyond the array's range.
