Why in %mem-ref/%mem-set is used (+ offset type-size) instead of (* offset type-size)?
I don't know. It looks like a bug, but this is a part of cffi-ecl.lsp which I still have not revised: I only changed convert-foreign-type to cffi-type->ecl.type
I don't understand exactly what SI:FOREIGN-DATA-RECAST is for here, but the OFFSET argument to %MEM-REF is a raw byte offset, not an element count, so adding it to the base pointer instead of multiplying it by the size seems like a reasonable thing to do here.
Luís, it looks like this was added in the patch "Updated ECL Support" about a year ago---do you remember why?
