GCC has two different alignments. It has a minimal ABI alignment and apreferred alignment. In the SYSV ABI for i386, the biggest alignment is32bit. It is beneficial for certain types to aligned more if it can bedone cheaply, that's why a global variable of type double for example isnaturally aligned.
