--- Comment #7 from Kevin Puetz <puetzk at puetzk dot org> --- Nope, falsified that guess - I just realized compiler explorer can do dwarfdump, which makes it easy to bisect among the releases they have (if not actually commit-by-commit). This shows that 9.5.0 (which has r263660) still produces bad DWARF, and 10.1 is fixed. So it can't be that commit... https://godbolt.org/z/jj4safe6e
