Hm. The closest I'm going to be able to get on Red Hat distros is one of

f22/gcc.spec:%global gcc_version 5.3.1
f23/gcc.spec:%global gcc_version 5.3.1
f24/gcc.spec:%global gcc_version 6.3.1
f25/gcc.spec:%global gcc_version 6.4.1
f26/gcc.spec:%global gcc_version 7.3.1
f27/gcc.spec:%global gcc_version 7.3.1
f28/gcc.spec:%global gcc_version 8.0.1

I'll try this on 7.3.1, since I already have that on a handy laptop.
But if it doesn't reproduce there I think the answer is going to be
that Debian is shipping an old buggy gcov.
