Time to revert GCC (with Epoch bump) to 4.9 in F22?
No, though I believe pushing GCC-5 into F22 was a mistake and pushing GCC-5 in to F23 at this point in time was a mistake, I also think it's too late to revert.

IMO, we have two alternative:
* "Close the eyes and pray", hoping there won't be any GCC-5 regressions which blow up F22 in a way, F22 will become unmaintainable/unfixable or will require a "partial mass rebuild" (E.g. because of hidden API/ABI changes or bugs).

* An F22 mass-rebuild, even though it is "this late in the cycle", even though this will likely cause a release delay and even though the persisting F23 GCC-5 issues will likely furtherly impact F22.
