            Bug ID: 102078
           Summary: ffinity.c:59:19: error: Signed integer overflow ?
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

Source code is

  for (index = 0; index < sizeof (unsigned) * 8; index++)
    if (mask & (1 << index))
      CPUSET_SET(cpuset, index);

maybe better code:

  for (index = 0; index < sizeof (unsigned) * 8; index++)
    if (mask & (1UL << index))
      CPUSET_SET(cpuset, index);
