--- Comment #22 from Ferdinand <ferdinandw+gcc at gmail dot com> --- Now that I understand the bug, of course I notice (too late) that my way of setting -g0 wasn't taking effect in the beta tree, the way it was before. So that explains that, but still this crash is happening with just -flto=4 (and default -flto-partition=balanced) for me. That means, at the moment, it's not latent for building firefox.
