            Bug ID: 97915
           Summary: ICE in get_odr_type, at ipa-devirt.c:1930 in pre
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: msebor at gcc dot gnu.org
  Target Milestone: ---

I see the following failures in the objc test suite today:

!  FAIL: objc.dg/lto/trivial-1 (2: +2)
!  FAIL: objc.dg/torture/forward-1.m (4: +4)
!  FAIL: objc.dg/torture/strings/const-str-3.m (4: +4)
!  FAIL: objc.dg/torture/strings/const-str-7.m (4: +4)
!  FAIL: objc.dg/torture/strings/const-str-8.m (4: +4)
!  FAIL: objc.dg/torture/strings/string1.m (4: +4)
!  FAIL: objc.dg/torture/strings/string2.m (4: +4)
!  FAIL: objc.dg/torture/strings/string3.m (4: +4)
!  FAIL: objc.dg/torture/strings/string4.m (4: +4)
!  FAIL: objc.dg/torture/tls/thr-init-3.m (4: +4)
!  FAIL: objc.dg/torture/trivial.m (4: +4)

The log has this output for the first test (the rest of them look similar):
