Actually, clang with libc++ works fine, and both clang and gcc with
libstdc++ don't...

If the problem is caused by the switchable libsupc++.so backend lib, I
would have no trouble with reverting that.  But do we know that for sure
at this point?  I have not spent enough time looking deeply into the
issue.

I did notice that libsupc++ .So objects get linked into libstdc++.so,
even while they are also in libsupc++.so.  Maybe that is causing trouble?
