--- Comment #4 from Vladimir Panteleev <dlang-bugzi...@thecybershadow.net> --- Actually, I believe we do count a breakage as a regression if something breaks for the end-user, regardless of what is going on under the hood. E.g. it's possible that for supported architectures, the range violation was completely benign. --
