Comment(by zbigniew):

 Unfortunately this breaks the ability of sha2 to digest any object other
 than strings such as blobs, srfi-4 vectors and even user-defined objects.

 Fixed the underlying problem in message-digest 2.0.3, which was that a
 length of -1 was being returned to digest procedures that didn't expect
 it, causing a segfault.  Now it signals an error.  So sha2 can safely
 digest any object again.
