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. regards, tom lane
