Hi all,

thanks to NSDebug I found two small memory leaks. However there's another one:
I'm loosing 2 instances of GSAutoreleasedMemory every few runloops.

I do not understand /usr/src/core/base/Source/Additions/GSObjCRuntime.m at the moment. So could anyone explain me the use of GSAutoreleasedMemory please?

GSAutoreleasedMemory is a private class whose instances are used to wrap an area of memory on the heap which is to be freed when the enclosing autorelease pool is deallocated. It should be impossible for this to be leaked unless you are running without an autorelease pool... in which case you should get lots of warning messages. Are you sure you are not misinterpreting things?
No. Of course I'm not sure :-)
However I'm also loosing an autoreleased local NSString. So I've a problem with AutorelasePools. However I do not get any "autorelease called without pool...." message. Perhaps I'm getting an exception in a background thread, which is not caught. In such a case the corresponding pool wouldn't be released. However the thread itself would exit. Could this cause the problem?
