Yes, that might be why Mans' subject line applies the adjective
'broken' to 'SPEC 2006' :-)  [also, for completeness: 4.8.0 actually
does not break things, a patch making it avoid doing so was
committed before release.]

The underlying point is a serious one, though -- the gcc tendency
to "adversarial optimisation" may be useful for helping us meet
our benchmark targets but it's not very pleasant to be the
programmer on the other side of it, when today's working program
silently breaks when compiled with tomorrow's gcc.
