--- Comment #6 from Paul Thomas <pault at gcc dot gnu.org> --- (In reply to Martin Liška from comment #5) > It's fixed on master with r12-3897-g00f6de9c691195. Many thanks, Martin. I'll try to apply it to 11-branch, if for no other reason than to see if it does so cleanly. Tobias must have thought that it was too invasive to backport. So I can keep track, September 2021: https://gcc.gnu.org/g:00f6de9c69119594f7dad3bd525937c94c8200d0 Paul PS How do you do this location - by hand or do you have a script to do the bisection?
