Well, my first guess would be that you have over-released some
object that was pulled from the app's Info.plist dictionary (via
CFBundleGet<something>), and that this is causing CF to crash
later when it tries to access an object that should be valid but
is actually dead.
You might try using the CFZombieLevel environment variable (search
developer.apple.com for more info) to disable deallocation of
released objects, see if that makes the crash go away, and then
you might be able to track down the object being overreleased.
Eric,
I think I was able to set this environment variable (to
0x00000010), and run but no luck. Crashing in same place.
MallocDebug only put up a dialog and said it crashed while trying
to access 0xdeadbeef - which seems like an allocation issue to me
as well. I just don't understand why this is happening though.
So, I started stepping through my init sequence, and noticed that
there were two CFRelease calls that I came across BEFORE the
crashing MenuManager code. Skipping over both of them in the CW
Debugger lead me to a successfully running MachO app - complete
with document window and all!!!
So, here's the code that WORKS in CFM and FAILS in MachO:
// cache our App-level resource file
CFBundleRef auxAppBundle(::CFBundleGetMainBundle());
// extract type and creator codes from it
UInt32 auxCreator;
::CFBundleGetPackageInfo(auxAppBundle, NULL, &auxCreator);
StResource appRes(auxCreator, (ResIDT)0); // could throw
mAppResFile = ::HomeResFile(appRes.Get());
// cleanup (FAILS in Mach-O) ##############################
#if TARGET_RT_MAC_CFM
::CFRelease(auxAppBundle);
#endif
What's the right thing to do here - release or not??? Is this a
bug in my logic (and ignored in CFM) but brought to the surface in
MachO?
THANKS to all who helped!
Mark
