            Bug ID: 57316
           Summary: [4.8 regresion] build failure in libsanitizer
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: sanitizer
          Assignee: unassigned at gcc dot gnu.org
          Reporter: PHHargrove at lbl dot gov
                CC: dodji at gcc dot gnu.org, dvyukov at gcc dot gnu.org,
                    jakub at gcc dot gnu.org, kcc at gcc dot gnu.org

On the same system where I reported bug 55989, I am now experiencing a build
failure in libsanitizer in the released 4.8.0.  As with that earlier bug,
libsanitizer is trying to use something low-level from Linux that did not exist
in older kernel versions.  In this case the "exit_group" systemcall.

I believe a colleague has seen the same problem in 4.8.1 snapshots.
