Re: Crash in CFRunLoopSourceIsValid

pthread_exit() will release the thread's retain on the run loop object. But won't destroy it unless that's the last retain.

In this case, move this line up into the previous if:
CFRelease(gStandardRunLoopRef);
to:
if ((runLoop != nil) && (kRunLoopCancelled != runLoop)) {
CFRunLoopStop( runLoop);
CFRelease( runLoop);
}
to take advantage of the parameter checking already going on there.

Chris,

I tried to change the code, but I now got another crash. Is it possible that
the pthread_exit() implicitly destroys the CFRunLoop?
