-Wstrict-aliasing only works if -fstrict-aliasing is enabled, so if you're
using -fno-strict-aliasing (or an optimization level below -O2 –
-fstrict-aliasing is only enabled by default at -O2, -O3 or -Os), you won't
get the warnings.
-fno-strict-aliasing is a workaround for production builds, but it also
sweeps the warnings under the carpet.
