I believe that it would be possible to construct some test cases with shared libraries built in the current regime, including only one version of the constructor, which will behave strangely in the new regime.
The ABI explicitly expects you to use multiple entry points, so either the ABI is broken, or the strangeness would come from some kind of undefined-ness.
However, the ABI does expect that if you have multiple constructor bodies for a constructor with vague linkage, then all of the copies are in the same COMDAT group. If I recall correctly, we never fully enforced that on all platforms, and if the copies aren't all in the same COMDAT group, then, indeed, I can imagine that you could end up with one of the constructors coming from one place, and one from another -- which might be unfortunate.
