Yes, I eventually found -fno-zero-initialized-in-bss, it does seem to have solved the problem. I'm just a little worried that some of the other stuff thats still in the bss might need to be zero too. But as of now I'm marking the bootldr as "working" when built with gcc 3.3, my latest sources are in svn on balloonboard.org (although note that I've renamed the dir from bootldr36 to bootldr). regards, Colin -- Colin Tuckley | colin@tuckley.org | PGP/GnuPG Key Id +44(0)1903 236872 | +44(0)7799 143369 | 0x1B3045CE A door is what a cat is perpetually on the wrong side of. - adapted from Ogden Nash
