<http://sbcl-internals.cliki.net/gdb> contains some (possibly
outdated) tips. Also, I noticed that libsane seems to have a lot of
debug statements along its code. I suggest you build a version of
libsane with those enabled. Since your program is segfaulting very
quickly, that should help in identifying the problem.
