            Bug ID: 107967
           Summary: The gcc commit 2f7f9edd28d caused the glibc make check
                    fails.
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: caiyinyu at loongson dot cn
  Target Milestone: ---

The gcc commit 2f7f9edd28d caused the following glibc fails with glibc
configuration on x86:
../configure \=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20
  CFLAGS=3D"-O2 -g" CXXFLAGS=3D"-O2 -g" \
                --prefix=3D/usr \=20=20=20=20
                --disable-werror

But when we changed "-O2" to "-O1", these fails passed.
