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);
}
#############
thread created 0
end thread 0
Segmentation fault (core dumped)
