If the test fails before the 15022 fix and passes after it, then it makes
sense to use the marker.

I don't understand why this is using RTLD_GLOBAL.
That does not seem to be material to this test.

(Incidentally, we write GLRO(dl_pagesize) with no space.  It's a special
case.)  This line and the large comment below are the same for the two
cases.  tststatic5 already tests that.  So this must be testing different
things that need to be tested, or else there is no point in the second test.
Its comments should say what exactly it is testing.


Thanks,
