Tests failing on macOS

[dishti]

Hi!
I'm trying to run Lucene++ on macOS Catalina. A large number of tests seem to be failing on mac (>100).

Some of them appear to be due to refCount issues:

And few of them due to exceptions not being caught correctly. Are there any other settings that need to be set to be able to run the tests successfully on mac?

I've actually forgot to run the tests. But now I did, and there's a lot of tsan hits, even after I fixed most (perhaps all) race conditions in conjunction with initialization of static variables (see #181).

[dishti]

Are these tsan hits different from the ones that you've submitted fixes for?

[kmatheussen]

I'm not sure. Some tsan hits might have been fixed by #183, but not all. All of the hits provided in #184 are run with the fixes in #183, so they are separate problems.

[kmatheussen]

But you might want to apply the patch in #183. Maybe that's enough to pass the tests, I don't know.

This patch doesn't seem to fix the test failures

3.0.8 passes all tests on 10.6 PowerPC. But fails to build on 14.2, ironically.
