I don’t know what pulls in the locale stuff or how to disable it. Your suggested flags makes a huge difference, it’s now 1424272 bytes in size, at 12% decrease from September and a 22% decrease from building the application with gcc 4.9.2 without the flags. I don’t see as much locale stuff in there. I only recompiled the user application code and not RTEMS itself. Even better the application still runs. How can these options change what gets linked in?
