You mean before or after the application of the suggested patch? Perhaps there may be other alignment 
constraints on powerpc-darwin than on i686-linux. The alignment with the ROUND-macro as i see it  
would not work with an alignment constraint any other than `alignment == multiple of data size'.
BTW: The bug is at least in gcc-2.7.2.3. I am wondering how it got along undetected, since the program 
with the encoding "{ii}" is an example taken from `Object Oriented Programming & the Objective-C 
Programming Language'. But however as i checked the various libs that are open source and compilable 
under linux (libFoundation etc.), nobody uses it. They all handle their serialization of compound object 
by themselves...
