[issue38628] Issue with ctypes in AIX

[David Edelsohn]

David Edelsohn <dje.gcc at gmail.com> added the comment:

How was Python compiled?  With GCC? Which version of GCC?
I assume that Python was built as a 64 bit application based on libc loading the 64 bit member shr_64.o.

Does the testcase work in 32 bit mode?
Does the testcase work if Python is compiled by XLC?

This likely is an incompatibility in libffi with libffi loading the registers incorrectly for the call into libc.a(shr_64.o).

It seems rather fragile to pass a struct that is supposed to have the same parameter layout as the function signature.
