No this is working as designed. GCC does warn about this case.
t.c:6: warning: dereferencing type-punned pointer will break strict-aliasing
rules
Now in 4.4.0 and above, the same result will happen at -O1 and -O2 because of
another optimization that allows for the compiler to remove the alias violation
in the IR.
