            Bug ID: 95582
           Summary: [11 Regression] LTO lean + PGO bootstrap is broken in
                    Ada
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: marxin at gcc dot gnu.org
                CC: rguenth at gcc dot gnu.org, rsandifo at gcc dot gnu.org
  Target Milestone: ---

Using:
../configure --enable-languages=c,c++,lto,ada --disable-multilib
--disable-libsanitizer --disable-werror --with-build-config=bootstrap-lto-lean
&& time nicem STAGE1_CFLAGS="-O2 -g" profiledbootstrap

I see the following ICE:
