Try compiling with -fno-strict-aliasing.  This is only automatically enabled at
-O2 or higher.  See the fine manual.

I'm not sure what you mean with "more efficient than memcpy".  If you mean more
efficient as in producing better code: Have you actually checked what comes out
of the compiler if you do this?  If you mean more elegant from a coding style
point of view: The language provides the means, it is called "union".
