[Gluster-devel] Segmentation fault on thread exit

[Dongmin Yu]

Hello,

When I run simple task on thread context, it causes segmentation fault on thread exit. I'm using glusterfs-3.0.2.

Here're my test code.

void* test2(void *aa)
{
    int a = *(int*)aa;
    glusterfs_file_t fd ;
    printf("thread created %d\n", a );

    fd = glusterfs_open( "/hs2/hello_thread.txt", O_CREAT|O_TRUNC|O_WRONLY, 666 );
    glusterfs_close( fd );

    printf("end thread %d\n", a );

    return 0;
}

void thread_test2()
{
    mount();
    int result;
    int i=0;
    pthread_t t;

    pthread_create(&t, NULL, test2, &i) ;

    pthread_join( t, (void**)&result);

}
