The difference is that the code you wrote actually is dumb, but relying on union aliasing is not. :) A behavior doesn't need to be defined by the spec as long as it is defined by the implementation (gcc) you are targeting.

The code I wrote was dumb... and yet Stroustroup repeatedly made a variant of the mistake in the "C++ Programming Language." Turns out that the use of operator<< in iostreams is problematic.
