I can't think of any reason why "ld" would care which kernel it was running under. I notice that your "ls" still works, and I doubt that "ld" does very much that "ls" doesn't do too, from the kernel's point of view. So I think your "ld" binary is corrupted. Just for interest's sake, it might be fun to run it under ktrace. -- John Polstra jdp@polstra.com John D. Polstra & Co., Inc.
