This is most likely caused by using older versions of libguile.h and
the other Guile includes when compiling your routines.  The mismatch
in binary type identifier between object file and Guile library causes
the effect above.

When I do the above in my 1.7 I, correctly, get:

guile> (array-prototype #i(1 2 3 4))
1/3
guile> (array-prototype #s(1 2 3 4))
1.0
