Chaque fois que je crée un pthread, valgrind émet une fuite de mémoire,pourquoi pthread provoque une fuite de mémoire
Par exemple le code ci-dessous:
#include <stdio.h>
#include <unistd.h>
#include <pthread.h>
void *timer1_function (void *eit){
(void) eit;
printf("hello world\n");
pthread_exit(NULL);
}
int main(void){
pthread_t timer1;
pthread_create(&timer1, NULL, timer1_function, NULL); ///////line13
int i=0;
for(i=0;i<2;i++){usleep(1);}
return 0;
}
sorties valgrind

pourquoi pthread_create cause de un problème bien que j'utilise la page man comme référence, et comment puis-je le réparer?
