--- Comment #23 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to Daniel Vollmer from comment #22) > (In reply to Iain Sandoe from comment #21) > I've tried this same reproducer using g++-8.3.0, also pre-built (bottled) by > homebrew, on darwin18.2.0 (so the same OS version but not necessarily > bootstrapping compiler as the failing 7.4.0), and that version also seems to > work fine. My freshly-built 7.4 (bootstrapped with 10.1 xc effectively) doesn't reproduce it, neither do any other branches I have lying around - so we're not there yet. I take it that the full code does fail with 8.3?
