That's weird. There is no FOREIGN-SYMBOL-POINTER symbol (without the
%) in cffi-ecl's CFFI-SYS package or any other CFFI-SYS package for
that matter. In any case, I can compile current CFFI with ECL 9.4.1,
without that patch. What ECL version are you using?

I do get some callback issues with ECL when running the test suite. I
haven't been able to figure out what's up, unfortunately. I suppose it
would help if you had a reproducible test case with CFFI and ECL's FFI
side by side. That would tell us who's at fault.
