Bug description:Integer overflow in SdnToJulian
Description:
------------
*cut*
void SdnToJulian(
long int sdn,
int *pYear,
int *pMonth,
int *pDay)
{
int year;
int month;
int day;
long int temp;
int dayOfYear;
if (sdn <= 0) {
*pYear = 0;
*pMonth = 0;
*pDay = 0;
return;
}
temp = (sdn + JULIAN_SDN_OFFSET) * 4 - 1;
*cut*
temp could here be less then 0 due to integer overflow (when sdn is large
enough).
Test script:
---------------
<?php
for(;;) {
$x = rand(0, 2147483640);
echo "$x\n";
$dummy = cal_from_jd($x,0);
$dummy = cal_from_jd($x,1);
}
?>
Expected result:
----------------
