>Description:
On amd64 platforms (tested with 6.2 and 7.0).
gmtime from libc doesn't returns to program if called with arg < -33884019326476800
May be we should return NULL?
>How-To-Repeat:
Simple program to test... first call return, second - loop forever...
#include <time.h>
#include <stdio.h>
void test(time_t t) {
struct tm *date;
printf("try %ld\n",t);
date = gmtime(&t);
printf(" ok\n");
}
int main(void) {
time_t time_ok = -33884019326476800LL;
time_t time_err = -33884019326476801LL;
test(time_ok);
test(time_err);
return 0;
}
