            Bug ID: 67568
           Summary: lto-streamer-in.c sanitizer runtime error: load of
                    value 255, which is not a valid value for type 'bool'
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: zeccav at gmail dot com
  Target Milestone: ---

Running make check in many test cases the sanitizer complains

../../gcc/gcc/lto-streamer-in.c:289:39: runtime error: load of value 255, which
is not a valid value for type 'bool'

The offending line is

 && current_col == stream_col && current_sysp == stream_sysp)

It seems that current_sysp has a value incompatible with its type bool
