Let's not forget that Debian is patch happy (as is Ubuntu, logically),
especially for gcc. Mostly for good reason but quite a bit is too
many diffs:

https://sources.debian.org/src/gcc-7/7.3.0-11/debian/patches/

It's quite possible that the snapshot plus diffs fixes/hides the bug
on Debian. Fedora is another distro that is very happy to carry
many diffs for some packages. Thinks of the version string like
git-gc-7.3.1+dirty in mainstream distros. It's like a downstream
branch.
