looks like the problem is in native/libffi/src/ffi.c. The version from 3.0.5 works, so something is wrong with the win64 patch.

If I revert this

- if (ecif->cif->rtype->type == FFI_TYPE_STRUCT) + if (ecif->cif->flags == FFI_TYPE_STRUCT) { *(void **) argp = ecif->rvalue; argp += sizeof(void*);

it still passes all the JNA tests, and mine. But

if (ecif->cif->rtype->type == FFI_TYPE_STRUCT || ecif->cif->flags == FFI_TYPE_STRUCT)

fails, so I _think_ that in my test case there is a time when

ecif->cif->rtype->type == FFI_TYPE_STRUCT

and

ecif->cif->flags != FFI_TYPE_STRUCT

and ecif->cif->flags is righter.

How do you cope with this stuff? I hope whoever pays you appreciates your talents!
