The program prints the expected result with both strict-aliasing and no-strict-aliasing on my x86_64 box. As such, when/why would I need to worry about this warning?

If you compile with -O3 -combine *.c -o alias it will break.


Thanks for pointing that out. But that's not a realistic danger for the actual application. The accessor function is always going to be in a library compiled at a separate time. The call will always be from a program built at a separate time, so -combine isn't a factor.
