Yes, for `(call/cc make-stack)'.  make-stack is supposed to be able to
construct a stack from a continuation, a debug object, or from `#t',
which means the current evaluation stack.  But the make-stack code was
missing a lot of the relocations that are needed in the
continuation case.  The symptom was a segmentation fault.

I forget now exactly how I discovered this, though.  Is it worth me
trying to dig that up?
