When changing a library name to one that is longer, and the .so file is too short, install_name_tool segfaults. This is rare and I can only reproduce it on a 64-bit build with one or two files. It may be a bug in the tools. The least intrusive change is to add a bit of minimum header padding on 64-bit systems. (Patch attached.) The chosen pad size of 128 is experimentally determined (32 is the minimum that works for me, and I added some fudge). It can be increased if required, at the cost of slightly bigger output files.

Doing

(module foo ()
  (import scheme (prefix chicken c:))
  (c:define-values (a b c) (values 1 2 3)))

fails, because define-values doesn't know about set!-values (it's SE is empty).
