-stable review patch. If anyone has any objections, please let us know.
------------------
There is an old bug in the pkt_count_states() function that causes stack
corruption. When compiling with gcc 3.x or 2.x it is harmless, but gcc 4
allocates local variables differently, which makes the bug visible.
