--- Comment #16 from Matt Godbolt <matt at godbolt dot org> ---
Just to be clear; I've been told GCC 6.2 is not required to compile the code I
linked; the earliest compiler it has been repro'd with is 4.9 (though we
haven't tested further back). It's also the mangled name created by the current
trunk of GCC 7.
