Compiles OK at -O2, but more slowly than with 4.1.2:
4.1.2 4.4.0
-O2:
real 1m19.827s real 2m58.945s
-O3:
real 1m30.645s real 10m5.166s
Even if -O3 ultimately generates correct code in some suitably large
configuration,
it may be that some optimizer
algorithms could stand tuning to avoid time-consuming
but ultimately unprofitable blind alleys.
