As for proposal to revert the aliasing fixes on the 4.2, IMHO aliasing
bugs are pretty nasty it is hard to find a option to work around because
alias info is used in many optimizations.
All bugs we are talking about can be worked around by using
-fno-strict-aliasing.
FWIW, in Apple distributed GCC 4.0.x, strict-aliasing is disabled by
default when -O? is used because it breaks too much existing
code (not just Apple internal code).
