My guess is that somebody slipped a clever optimization into the x86-64
gcc runtime library that triggered this behavior.

I have seen several instances in open source projects in general, and
gcc in particular, where a smug developer has intentionally inserted a
change that, although technically correct, breaks previously working
(but invalid) code. "This'll teach the little buggers..."
