             Bug #: 50532
           Summary: [patch] libffi needs FFI_MMAP_EXEC_WRIT on
                    kfreebsd-amd64
    Classification: Unclassified

          Severity: blocker
          Priority: P3
         Component: libffi
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: Petr.Salinger@seznam.cz
