This is how he described the problem:

The problem seems to be that the system call that is used to load the
thread structure of a group from the file system is unable to do this, even
though the iOS system call to save this structure to the file system has
done so without any issue. The problem seems to happen only for extremely
deep nested threads. When saving these deeply nested structures iOS reports
no error, but when reading them, iOS reports an error.

Oh well. Must be using some built in iOS data serialisation API. Should have
just written a normal file using json or some similar standard format but
20/20 hindsight etc.



Apparently he's creating his own alternative to the iOS system call he was
using, on the assumption that Apple will be slow to fix it.
