Anyways, the CFRunLookFindMode/CFRunLoop crash that I came across
is somewhat in limbo right now.
From the best I, and an Apple QA Engineer, could diagnose,
something was fiddling with the Core Foundation shared library
space. While I still have a sneaking suspicion that there is a bug
lurking around in there, the main problem that was causing my
issues was that Chax[1] was doing something nasty that it shouldn't
have been doing, and thus crashing Core Foundation, and taking some
of Apple's applications that were intimately tied to CF at the time
along with it (in my blog posting, Preview and Mail.app)
That's interesting. My dev system is pretty stock, but I have seen
Mail.app go down quite a few times while I've been debugging. I was
already beginning to suspect some connection.
I can reliably replicate the issue (and another possible multi-
threading issue with NSUserDefaults that I posted about earlier).
While the bug in radar may or may not be closed right now, I still
_think_ there is an issue in CFRunLoop, so if you could post sample
code to where we could isolate the bug I would be more than happy
to pitch in and help break it :)
Currently, I'm trying to replicate the issue by modifying the
SimpleThreads example. My Multi-threading code was based on that, and
if I can cleanly replicate there, then it saves me paring off more
cruft and/or proprietary code from my test case.
Of course, you could just give up on CFRunLoop and put all your
code into a big ol' while (true) {}.... just a thought :-P
if only
cheers,
