Generally if you have troubles running something on ARM, ensure that
there are no alignment problems first. You can read the following
wiki page for the details: http://www.nslu2-linux.org/wiki/Info/Alignment
So you can run 'echo 3 > /proc/cpu/alignment' as root, start the program you
want to debug and check if it works better (but any misaligned memory access
will be very slow). Checking 'dmesg' log will reveal the addresses where you
had misaligned memory reads or writes.
