Hi all,

When using a timer I seem to be getting a memory leak.
It eats up about 8 kilobyte per second.

Here's some example code:

#include <stdio.h>
#include <pthread.h>
#include <signal.h>
#include <stdlib.h>
#include <unistd.h>

void nothing(){}
void Die(char *error){perror(error); exit(1);}

int main()
{
    struct itimerspec itimer;
    struct sigevent sigev;
    timer_t timer;
    int interval = 16000;
   
    itimer.it_interval.tv_sec = interval / 1000000;
    itimer.it_interval.tv_nsec = (interval % 1000000) * 1000;
    itimer.it_value.tv_sec = interval / 1000000;
    itimer.it_value.tv_nsec = (interval % 1000000) * 1000;
   
    sigev.sigev_notify = SIGEV_THREAD;
    sigev.sigev_notify_attributes = 0;
    sigev.sigev_notify_function = &nothing;
   
    if (timer_create (CLOCK_REALTIME, &sigev, &timer) < 0)
        Die("timer_create");

    if (timer_settime(timer, 0, &itimer, NULL) < 0)
        Die("timer_settime");   
   
    while(1) sleep(1);
}
