Depending on how the serializer is used, this may result in an
unaligned write. You can check whether an alignment error is involved
as follows:
echo 5 > /proc/cpu/alignment
and re-run the executable that's causing trouble. The program should
receive a signal (so you can see where exactly things go wrong in gdb)
and the kernel should report an "Alignment trap: ..." on the console or
in dmesg/syslog.
Cheers,
Rene
