Disable GCC “may be used uninitialized” on a particular variable

Question

I\'m getting this warning on a stack variable:

warning: object.member may be used uninitialized in this function

In this case I do not wish to

GCC differentiates between uninitalised and self initalized, e.g. compiling:

int main() {
   int i = i;
   return i;
}

With gcc -Wall -Wextra gives no warnings, unless you explicitly added -Winit-self as well, yet it gets completely optimized out by my quick testing.
