This isn't the case here, the only stack alignment is done in main(). I'm using binutils 2.16 if that helps. ___________________________________________ I suppose it helps a little, because broken binutils I have seen had older versions than that. Somewhere along the line, if you said what environment you were using, I missed it. It looks like others have figured out you were using mingw32, with which I have relatively little experience. I haven't looked to see whether mingw binutils is generally built with only 4-byte alignment support, as cygwin used to be. Not only did that break SSE, it made doubles slow. Tim Prince
