            Bug ID: 31621
           Summary: struct utmp, struct utmpx, struct lastlog may change
                    size in time64 mode
           Product: glibc
           Version: 2.40
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: fweimer at redhat dot com
          Reporter: fweimer at redhat dot com
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

On i386 and other architectures, struct sizes change with -D_TIME_BITS=3D64=
. This
should not happen because these structs describe file formats in /var/log, =
and
the system processes that maintain them are likely built without
-D_TIME_BITS=3D64.
