When my app runs in Mavericks (10.9.5), it crashes on quit, but in High
Sierra it's fine.  The backtrace doesn't show any of my code, so I'm not
sure how to proceed.  I don't suppose this means anything to anyone?

Have you tried ASan and TSan?  10.9 is even old enough to support valgrind I 
think.

OK, I tried a build made with ASan, and there was no difference. With TSan, I get a dyld Symbol not found error on _OSAtomicDecrement32 being referenced by the tsan dylib.
