The problem appears to be with a confusion over the definition of struct utmpx
in bits/utmpx.h. If you check the #if statement on line 70 in bits/utmpx.h it
evaluates "#if __WORDSIZE == 64 && defined __WORDSIZE_COMPAT32" to true, and
defines struct ut_tv to...

     72   struct
     73   {
     74     __int32_t tv_sec;           /* Seconds.  */
     75     __int32_t tv_usec;          /* Microseconds.  */
     76   } ut_tv;                      /* Time entry was made.  */

Instead of...

     79   struct timeval ut_tv;         /* Time entry was made.  */

Furthermore, if you check the sizeofs of utmpx.ut_tv and struct timeval, you get
8 and 16 bytes respectively. dm/utmpentry.c appears to be thinking ut_tv is of
type timeval, which in this case it is not. Now correct me if I'm wrong but I
don't have multilib enabled, but __WORDSIZE_COMPAT32 is set, this confuses me.

64bit-only issue ... fixed in cvs now
