I don't believe it has anything to do with optimization; rather, it is to do with lack of `warning' flags. For example, if you build libc with WARNS=5 (so as to get the `-Wuninitialized' flag), then you get this warning. > "x.c:9:warning: `foo' might be used uninitialized in this function" Cheers, -- Jacques A.
