Fix this by unreferencing objects after calling objlist_call_fini() in dlclose(). Therefore objlist_call_fini() now calls the fini function if the reference count of an object is 1. In addition we must restart the list_fini traversal after every _fini() call because another dlclose() call might have modified the reference counts. Add an XXX comment to objlist_call_fini() about possible race with dlopen(). PR: 133246, 149464 Reviewed by: kan, kib |
