        <pre>Note that GCC's warning says "may be used uninitialized", not "is used
uninitialized". The clang warning flag for that is -Wconditional-uninitialized.
That gives:

<stdin>:9:12: warning: variable 'result' may be uninitialized when used here
[-Wconditional-uninitialized]
    return result;
           ^~~~~~
<stdin>:6:17: note: initialize the variable 'result' to silence this warning
    char *result;
                ^
                 = 0

llvm-g++ is not supported, so we don't care what it does here.</pre>
