#15 test_int (__main__.Callbacks) fails on Mac OS X

[francesco pierfederici]

Hi,

I have installed ctypes from CVS (as of March, 29,
2005) on a Mac OS X (10.3.8) box with the stock Python
installation (2.3).

Compilation went fine, but then one of the unittests fails:
tiamat> python test_callbacks.py -v
test_byte (__main__.Callbacks) ... ok
test_char (__main__.Callbacks) ... ok
test_char_p (__main__.Callbacks) ... ok
test_double (__main__.Callbacks) ... ok
test_float (__main__.Callbacks) ... ok
test_int (__main__.Callbacks) ... Illegal instruction

Cheers
francesco

FYI, all other unittest work.

I would need help to fix this. Windows is my primary
development platform, and I'm not really up to speed with
gdb on OS X.
For me, the exact test that is failing depends on how I run
the program - sometimes it crashes in test_char_p, or
somewhere else.

If I insert print statements somewhere in the C code, it
doesn't crash anymore ;-).

I guess it would help to build libffi with debug info, but
currently I don't know how to do this.

Should be fixed in CVS now, mainly by moving to a newer
version of libffi (which is in ctypes CVS).

BTW: If you want to build from CVS, you should check out the
'branch_1_0' branch for the stable version.
