Basically, as I understand it, if you're using any code that uses
custom allocators, which are used by a lot of stuff (quicktime and
lots of security code, but lots of othr stuff as well, probably), you
can forget objectalloc. OmniObjectMeter suffers from similar problems.
If you can cut the stuff with custom allocation out of your app, you
may be able to debug the rest. I was able to do this when I was using
some ssl and other security stuff, but in my quicktime video capture
app, it would be kind of pointless.
Heap and leaks should still work though, and are sometimes easier to
work with than the graphical apps.

When I try to use ObjectAlloc to launch my app, my app crashes. I am shown
the dialog "The subtask was terminated by signal 11." There is a crash log,
which starts like this:
Thread 0 Crashed:

[...]
My applicationDidFinishLaunching: does indeed have a presentError: call, but
I don't understand why the error is even trying to appear, since it does not
appear when I run or debug the app without ObjectAlloc in the story.
The problem seems to have to do with QTKit and loading a QTMovie. If I
comment out the code that loads the QTMovie, the problem vanishes. Is there
some known bad interaction between ObjectAlloc and QTKit?
