AIX -illegal instruction - importing extension module

[Ajay Bakhshi]

Hi,

I am getting the following problem on AIX.
I create a small shared library. And tried to load it in python.

It core dumps with the following message:
Segmentation fault (core dumped)

At other time with another shared lib I got:
Illegal instruction: core dump

* The program works fine on hp-ux 11.11 and solaris 7.

NOTE:
* python - version: 2.2.3 is compiled with cc_r (Visual age 6.0 compiler)
it is ##### 64 bit ######
* AIX 5
* I compiled the shared lib with xlC, cc_r and g++ to see if the compiler
was an issue
* Also note that: when I copy the pwd.so from lib-dynload/pwd.so and moved
lib-dynload/pwd.so to lib-dynload/pwd.so.org and then imported pwd.so it
when through fine.
* When I wrote a C main() program to load the shared library and load the
symbol using dlopen and dlsym it worked fine.
The python program is:
=========================================
import os, sys
print "before import libspam"
import libspam ====> It dumps here
print "after import libspam"
print OK.
=========================================

The shared lib code is also very simple

================================================== ===============
PyObject *
spam_system(PyObject *self, PyObject *args)
{
char *command;
int sts;

printf("\n In spam_system \n");
if (!PyArg_ParseTuple(args, "s", &command))
{
printf("\n spam_system: FAILURE");
return NULL;
}
sts = system(command);
printf("\n spam_system: SUCCESS");

return Py_BuildValue("i", sts);
}

static PyMethodDef mmdb_methods[] =
{
{ "spam", spam_system, METH_VARARGS,
"mmdb.control( allow_fail, allow_fall_back ) -- Control the
kind of client that is created"
},
{ 0, 0, 0, 0 }
};

PyObject * initlibspam(void)
{
PyObject *module = Py_InitModule3("libspam", mmdb_methods, "Test Spam");

return module;
}
================================================== ===============
