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/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):
