However, the failure you're getting implies that at least _some_  calls
into C are working.  The fact that it is able to print the list of files
means it successfully invoked write() in libc.

When you get this error:
   SC: 0, Offset: 30  0x0000004e: other immediate 1, unbound-marker
    SC: 3, Offset: 9 $1=  0x50775c6b: list pointer
Can you try 'p 0x50775c6b' (substituting in the actual value of that
pointer if it is not this) to get a little more information? I'm slightly
confused why UNARY-TRUNCATE-SINGLE-FLOAT-TO-BIGNUM is trying to signal a
type error about an object the name of whose type is a list.  Also, if I
purposely call unary-truncate-single-float-to-bignum with unbound-marker,
then I get a fairly hard crash (which is reasonable since it is
system-internal), and not a type error.
