Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Priority|P3 |P1 Component|rtl-optimization |middle-end Target Milestone|--- |8.3 --- Comment #11 from Richard Biener <rguenth at gcc dot gnu.org> --- Needs more investigation (ignore my previous comment - main() is not really relevant here). This is a very recent regression on the branch. You can do -fdisable-tree-ealias and still get the failure but less early IL changes when comparing to -fno-tree-pta.
