Debugging crash in _class_shouldFinalizeOnMainThread


  • Subject: Debugging crash in _class_shouldFinalizeOnMainThread

I'm getting intermittent crashes in my test suite for a GC application
on OS X 10.6.4. The KERN_INVALID_ADDRESS at 0x0000000900000028 occurs
in

 0   libobjc.A.dylib               	0x00007fff82ac847b
_class_shouldFinalizeOnMainThread + 4

within the Dispatch queue: Garbage Collection Work Queue thread.

This application makes heavy use of third-party C++ libraries, so I
assume that the problem is in my memory management of C++ within a GC
app, but I'm not sure where to start the debugging process. Since GC
is running on a separate thread, the debugger doesn't stop at a
particularly useful place. Can anyone point me in a useful direction?
I'd be happy to provide more details if there's relevant information
I'm leaving out.

Thanks,
Barry
