Follow-up Comment #4, bug #22246 (project gnustep):

The diagnosis may well be correct, but the I simply can't be sure from
looking at the example program.
The problem is that the test program is not the simple testcase for KVO I was
looking for, but instead implicitly includes all the gui bindings stuff ... so
without a clear understanding of bindings (and a surety that they are
implemented the same way in macos/gnustep) it seems impossible to tell whether
the difference in behaviors of the test app on the two systems is caused by a
difference in KVO implementations or a difference in KVB implementations...
That is to say, it's a test to demonstrate a gui bug without demonstrating
whether the bug arises in the gui (KVB) or from an underlying fault in base
(KVO).
I guess I'll have to look at the KVB code to see exactly what it does and
produce a testcase for KVO.
