Continuing. In here…
http://opensource.apple.com/source/libdispatch/libdispatch-228.18/os/object.h
I find a maze of #define compiler directives which affect OS_OBJECT_USE_OBJC_RETAIN_RELEASE, and also there is a comment which implies that maybe I should add compiler flag -DOS_OBJECT_USE_OBJC=0 to the file which invokes xpc_release(). Indeed, doing so fixes the error.
But I don't fully understand what the effect is. Also, my little project does not have that flag, neither as an option in the relevant source file, nor anywhere in Build Settings. It builds fine without it.
Any clues to the intended usage of this OS_OBJECT_USE_OBJC_RETAIN_RELEASE and OS_OBJECT_USE_OBJC would be appreciated.
Thanks again,
Jerry
