This bug is now fixed by 
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=3730793d457fed79a6d49bae72996d458c8e4f2d

Could you please include this patch in the next -stable releases?

BTW: the problem exists in gcc-4.2.4 not gcc-2.4.2 so I think it is 
worth to change the subject when adding the patch. ;)

Best regards,
