Hi,
I have an Objective-C/Cocoa app with garbage collection enabled. To
check for memory leaks I first ran it through Instruments and it did
find some leaks. There was no information on where the leaks were
coming from, so I used another tool, AnalysisTool (basically a front
end for the Clang Static Analyzer) to check my code for memory issues.
It found some leaks and I fixed all of them, however Instruments still
reports leaks.
Further complicating the problem is that my app crashes when garbage
collection is disabled. And in the Xcode debugger console (when
garbage collection is enabled), right when my app starts I get these
errors:
MyApp(9874,0xb0103000) malloc: free_garbage: garbage ptr = 0x101bfb0,
has non-zero refcount = 1
MyApp(9874,0xb0103000) malloc: free_garbage: garbage ptr = 0x101ec90,
has non-zero refcount = 1

Any help with this would be appreciated. Source code is available upon
request
Thanks
