First of all, thank you for making these bindings available. They are
great! Much better that the bare-bones cffi wrappers I've been using for
the small subset of gsl I've needed.
I think there is a small bug with exceptions in the code. I usually make
my own image with code that I use regularly (sbcl 1.0.14), i.e.
(require 'asdf)
(require 'asdf-install)
(require 'cffi)
(require 'gsll)
(sb-ext:save-lisp-and-die "sbcl-with-slime.core")
then start up sbcl with "sbcl --core sbcl-with-slime.core". In this mode
of operation gsll hangs when an exception is caught, e.g.
(jacobian-elliptic-functions 0.61802d0 1.5d0)
just sits and the repl prompt is not returned (endless loop or something).
If I just fire up sbcl and load gsll normal everything works fine and I
get the expected warning that |m|>1.
Hope this is a useful enough description of the problem for you to track
it down.
With kind regards,
Jason
