Sorry if I wasn't clear--the original assembly difference I posted in (https://bugs.python.org/msg362665) was indeed using the "release" build configuration. My last comment was trying to demonstrate this fact by showing that the assembly output would have looked different if I had selected the "debug" build configuration. 

Is there something I'm missing, or was Visual Studio just missing an opportunity to optimize?
