This has been reported to upstream lcov community every time they break on new GCC releases & I've backported fixes to Fedora once they are available. Most recently I reported the incompatibility with gcc9 way back in January this year https://github.com/linux-test-project/lcov/issues/58 I can't do anything to fix lcov in Fedora until upstream provides the fixes.
