--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Matthias Klose from comment #3) > --without-build-config doesn't make a change. Building that on Ubuntu 26.04 > for z15 succeeds. I'm confused. So adding --without-build-config fixes the miscompare? But doesn't make a change? Or do you say building for z15 succeeds (with or without --without-build-config?) but adding --without-build-config to the original failing case (which was not z15?!) still miscompares?
