Comment (by jwhowarth):

 Also I would note that python up to 3.6 still uses -fno-strict-aliasing
 because, while its own code may have been cleaned up to be strict aliasing
 safe, it can't depend for that to be true for all the python modules for
 which it sets the compile flags. Again, all of this is entirely orthogonal
 to why we are using it in pymol which is an unrelated clang compiler bug
 in that case.
