An interesting exercise might be to
code up a small program to call adjtimex with timex.status |= STA_INS,
to see if this can trigger the problem.
Setting the date to just before midnight June 30 UTC and then running the
following as root triggered the crash on a modified 2.6.10. Anyone see anything
wrong with the code below, or is this a valid indication of a bug in the leap
second code?

#include <sys/timex.h>
#include <stdio.h>
#include <errno.h>
struct timex buf;
int main(void)
{
int rc = adjtimex(&buf);
printf("initial status: 0x%x\n", buf.status);
buf.status |= STA_INS;
buf.modes = ADJ_STATUS;
rc = adjtimex(&buf);
if (rc == -1) {
printf("unable to set status: %m\n");
return -1;
} else
printf("rc: %d\n", rc);
printf("final status: 0x%x\n", buf.status);
return 0;
}
