            Bug ID: 57563
           Summary: Lots of Cilk+ failures on i686-linux
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jakub at gcc dot gnu.org
                CC: bviyer at gcc dot gnu.org
            Target: i686-linux

If you do
make check-gcc RUNTESTFLAGS='--target_board=unix/-m32 cilk-plus.exp'
on x86_64-linux (or just make check-gcc RUNTESTFLAGS=cilk-plus.exp on
i686-linux), I'm seeing tons of FAILs that don't show up in x86_64 64-bit
