Stefan Krah <stefan-use...@bytereef.org> added the comment:
The segfault occurs both with CFUNCTYPE and PYFUNCTYPE in
ffi_prep_incoming_args_SYSV(). I'm not very familiar with
either suncc or the dbx debugger, and I can't get dbx to
step into that function (compiled with -g, libffi is not
stripped as far as I can see). Anyway, here's what I got:
(dbx) stop at ffi.c:403
(2) stop at "ffi.c":403
(dbx) run
Running: python
(process id 29932)
Python 3.3.0a0 (default:5c8b6e03ebfe+, Sep 7 2011, 15:48:46) [C] on sunos5
