This means that the code produced by GCC 2.7.2.x will sometimes run 
faster and sometimes slower that the code of 2.8.1, since the actual 
alignment is determined by pseudo-random factors, right?

Is the problem limited to .bss data?

Can't we change the alignment parameter in Binutils configuration?
