iOS, app randomly crashes on startup

Question

From a few days my new project crashes during startup iOS Simulator. However, if starts then works properly.

Error(Thread 1: signal SIGABRT) is shown for these steps:

0:

0x9171ba6a:  jae    0x9171ba7a                ; __pthread_kill + 26

1:

0x94093b2f:  cmpl   $-1, %eax

2:

0x196757b:  jmp    0x19675aa                 ; abort + 187

3:

GraphicsServices`GSRegisterPurpleNamedPort:

4:

0x226e69f:  movl   %eax, 51254(%edi)

5:

0x226ec1f:  addl   $24, %esp

6:

0x2bfd99:  movl   7636317(%esi), %eax

and in the main.m: 7:

return UIApplicationMain(argc, argv, nil, NSStringFromClass([cysAppDelegate class]));

What can cause this error?
