>Description:
Call to shm_get() produces:
Bad system call (core dumped)
>How-To-Repeat:
make this program:
#include <sys/types.h>
#include <sys/ipc.h>
#include <sys/shm.h>
int main()
{
key_t key = 6575;
int area_a_id;
#ifndef SHM_R
#define SHM_R 000400
#define SHM_W 000200
#endif
/* set up shared memory regions */
area_a_id = shmget(key, 64*sizeof(double),
IPC_CREAT|SHM_R|SHM_W|(SHM_R>>3)|(SHM_R>>6));
return 0;
}
/* works fine in 2.1.0-R, but cores in 2.2.1-R */
