Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |ice-on-valid-code --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- If it doesn't happen with the stage1 compiler (maybe configury is slightly different, can you check it successfully builds with the stage1 cc1?) it sounds like stage1 miscompiling the stage2 compiler.
