I may be stating the obvious here, but the -1, which is declared to be
of type 'scm_t_int8' in the C function being called, is apparently being
interpreted as 255.  This suggests that whatever is handling its
promotion to a full int is failing to extend its sign bit.  I'm guessing
that this is libffi's job.

Hans: can you please verify that your libffi's 'make check' passes all
tests on your platform?  If it passes, and if this ends up being a
different build of 'libffi' than you were previously using, it would be
helpful if you could install the newly-built 'libffi', then do a fresh
rebuild of Guile 2.0.5 and see if that fixes the problem.

     Thanks,
       Mark
