[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);

 

}

 

#############

thread created 0

end thread 0
