I completely disagree. Dropping the optimization is at best a workaround.
IMHO it can ''never'' be "the right solution". It means that either the
compiler or the code has a bug. Maybe dropping the optimization to `-O2`
covers up any issues, but I think one should really investigate what the
true problem is.
I am ''very strongly'' against saying to never increase the optimization
level to `-O3`. If some later upstream version has fixed this problem, we
''should'' increase the optimization level back to `-O3`.
