I see now I missed a sizeof() when I did the above (sorry!), and you 
fixed it.

However, today you implented almost identical problematic unaligned code 
in django's binary(). Are we going to go through this everytime? My 
explanation above holds true for any format. Fix this (just like it is 
in RACF now), and please do not re-implement this exact bug again in 
other formats.
