Excellent!

At last! Note that the above was not a g-golf problem [1].

And for that matter, nor is (a g-golf problem) the patch i just added
to adapt to a GI/libffi api change that i was unaware of [2] - up to
this upstream api change, g-golf has never failed to build and run an
ffi-closure, ever since it implements callback and vfunc, all (the
closure marshal machinery) entirely written in scheme by the way.

[2]

the gi doc tells us switch to call g-callable-info-create-closure when
using gi >= 1.71.0, but fails to tells us that, starting with gi >=
1.72.0, the ffi-closure pointer we receive is no longer a 'native
executable code pointer' ...
