You didn't show a complete example though, so we have no idea what the rest of your program does. I suggest you try the steps recommended before reporting a bug: "Before reporting that GCC compiles your code incorrectly, compile it with gcc -Wall -Wextra and see whether this shows anything wrong with your code. Similarly, if compiling with -fno-strict-aliasing -fwrapv -fno-aggressive-loop-optimizations makes a difference, or if compiling with -fsanitize=undefined produces any run-time errors, then your code is probably not correct." You could also try -fsanitize=address or valgrind to check for memory errors (but don't use valgrind on code compiled with -fsanitize=address, use one at a time).
