            Bug ID: 66241
           Summary: ICE: verify_type failed while building libstdc++
                    (dwarfout.c: gen_type_die_with_usage())
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vp at gcc dot gnu.org
  Target Milestone: ---

I'm seeing this while building arm-none-linux-gnueabi/gnueabihf at the stage of
building libstdc++

[...]arm-none-linux-gnueabi/libc/usr/include/bits/types.h:134:30: internal

This looks similar to bug 66214 but not sure if it's the same. Attaching a
preprocessed file that reproduces this with g++ -g -O0
