      We currently disable the compilers alias based optimziations by building with -fno-strict-aliasing, due to a small number of aliasing violations.

      The majority of these aliasing violations are in the mmap subsystem.

      We should switch the default to build with type based alias analysis enabled, and only disable it for subsystems which require it.
