--- Comment #23 from Michael Catanzaro <mcatanzaro at igalia.com> ---
Zan did some investigation today and found that the upstream GCC 7.3.0 release is broken, but the problem is fixed somewhere on the GCC 7 subversion branch.

If Miguel was careful to test the same WebKit revision so as not to get tripped up by the revert of Yusuke's std::optional commit, then I'm guessing the fix landed in February or early March. gcc (GCC) 7.3.1 20180130 (Red Hat 7.3.1-2) is of course a January 30 snapshot, so we know that's broken. And gcc version 7.3.1 20180303 (Red Hat 7.3.1-5) is March 3.

Debian 7.3.0-17's is an April 27 snapshot. You can see the history here:

I don't know if Debian makes it easy to test old packages, but the granularity there is way smaller than what we have available in Fedora (which is just January 30 and March 3).
