            Bug ID: 70366
           Summary: chromium fails to build with LTO due to segfault in
                    ipa-inline-transform.c:inline_call
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ipa
          Assignee: unassigned at gcc dot gnu.org
          Reporter: prathamesh3492 at gcc dot gnu.org
  Target Milestone: ---

I tried building Chromium with LTO for arm-linux-gnueabihf and resulted in
segfault.
Backtrace:
http://pastebin.com/sX6yKLBP
Looks like it's probably caused by r231095.
Reverting that commit prevented the segfault.
