[STR Closed w/Resolution]

One thing I realized later, the crash as described above depends on stack[]
being located above the table[][].  If memory allocator places it below,
stack[] overflow can result in table[][] modification, which can break the
infinite loop, and the program may continue executing with corrupted heap.
