Using memcpy (which is provided by lots of different OSes and C libraries) does not force your program to be 'open source' as far as I know, or 
according to any legal opinion I've ever heard.  If your lawyers say differently, that's really not our problem.  

Anyway, like (nearly) all optimizations in gcc, it can be turned off by turning off optimization for the affected file.
