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?

Chris


#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;
}
