IO-related error #73

Closed buffpojken closed 9 years ago

buffpojken commented 9 years ago

I've started to see a lot of crashes which I think is cdq/Core Data-related. Seemingly at random, when accessing objects inheriting from CDQManagedObject, the application crashes with the log posted below.

Behaviour has not existed prior to updating RM to 3.3, therefor I'm hesitant to mark this as a definite bug in CDQ, but I've no idea how to proceed.

I'm not seeing which part makes you suspect CDQ is involved...

buffpojken commented 9 years ago

Actually, I only suspect CDQ being involved because it's the only explicit IO being performed in non-Apple libraries. If you think this has nothing to do with CDQ, I'll happily close it and pass it on to Hipbyte.

fermion commented 9 years ago

I observed something similar, just filed an issue with Hipbyte about it. Mine was when accessing particular attributes of cdq models (it doesn't like "description" as a property name). My trace looked more like:

Mar 22 14:35:59 Robs-iPhone ReportCrash[6020] <Error>: task_set_exception_ports(B07, 400, D03, 0, 0) failed with error (4: (os/kern) invalid argument)

If anything comes if this I'll update this issue.

fermion commented 9 years ago

Nevermind, here's my problem:

Compile ./resources/HealthAxioms.xcdatamodeld
/Users/rsterner/code/rcllc/HealthAxioms/resources/HealthAxioms.xcdatamodeld/0001 initial.xcdatamodel:HealthAxiom.description: warning: description conflicts with a method already on NSObject or NSManagedObject [4]

Missed this during the many times I've run the app during dev!
