Unfortunately this commit breaks my build and executable. FC 18. --enable-debug
and --enable-wccp.
Building:
autoreconf -i
fails.

When I tried to run it with just a normal rebuild (I tried autoreconf in case
there was a configuration problem), I get
Program received signal SIGSEGV, Segmentation fault.

I don't see why it segfaults - in the debugger in frame 0 I can look at mem and
*mem without a problem. Does the 128 int have to be naturally aligned?
