After adding traces and after rebuilding Python and libffi with -O0 -g -gdwarf, it appears that, still in 64bit, the bug is still there, but that ffi_call_AIX is called now instead of ffi_call_DARWIN from ffi_call() routine of ../src/powerpc/ffi_darwin.c (lines 915...).
???

# ./Pb.py
TONY: libffi: src/powerpc/ffi_darwin.c : FFI_AIX
TONY: libffi: cif->abi: 1  -(long)cif->bytes : -144  cif->flags : 8  ecif.rvalue : fffffffffffd1f0  fn: 9001000a0082640  FFI_FN(ffi_prep_args) : 9001000a0483be8

None

In 32bit with same build environment, a different code is run since the traces are not printed.

Thus, 32bit and 64bit are managed very differently.
