Why?  If so it makes more sense to convert your databases to skiplist
and see if that helps than to flop library versions.

Maddly flipping versions seems a poor diagnostic method (if it even
qualifies as a diagnostic method).

The best approach is to switch to a distribution where things are tested
and shipped in a known-working binary (w/dependencies) built by people
who actually understand what the various compiler options mean, etc...
Your method of shut-gunning various library versions isn't very likely
to lead you to a solution.
