The official commission that investigated the case immediately after the incident said that the causes of the deaths were ' not known ' . Moreover , the Federal Bureau of Investigation and other intelligence agencies that investigated the 1993 bombing and the subsequent residence in Iraq of Abdul Rahman Yasin , a low-level suspect , found no evidence that Baghdad was actively protecting him or that he was linked to Iraqi intelligence in any way . Some common situations that may prevent the reference count of an object from going to zero include : circular references between objects ( e.g ., a doubly-linked list or a tree data structure with parent and child pointers ) ; a reference to the object on the stack frame of a function that caught an exception ( the traceback stored in sys.exc_traceback keeps the stack frame alive ) ; or a reference to the object on the stack frame that raised an unhandled exception in interactive mode ( the traceback stored in sys.last_traceback keeps the stack frame alive ) . This effort resulted in a FCA approach that utilized a multi-disciplinary team of architects and engineers , working in close conjunction with , and receiving valuable input and assistance from facility engineering staffs , that visited every Medical Center in the VISN to perform the survey .
