Thanks for giving it a try!  It's a bit embarassing that this didn't
work, but I did track down the issue today.

Some parts of Guile want byte arrays aligned on 8-byte boundaries.  We
use __attribute__((aligned(8))) on GCC to do that.  Probably your
compiler has something similar; it would be great if you could
contribute a patch to libguile/__scm.h to define SCM_ALIGNED there.

We do have a fallback that involves mallocing a buffer, and copying the
unaligned buffer into the malloc'd buffer.  That code was not working in
a couple of cases.  I think I have fixed it; at least, I tried it out
locally, and it worked for me.

Thanks for the report,
