Import of strop module in C program with Python2.2 on AIX4.3.3 issues a segmentation fault

[Olivier Cipière]

Hi all,

Here is a problem I encounter with Python 2.2 on AIX 4.3.3 :
The import of strop module or strop dependants modules 
in a C program issues a segmentation
fault, even though it seems to work alright when performing 
import from the python prompt.

Does anybody have already encountered this problem or have a solution ??

Best regards,

Olivier Cipière.

Below is the simple test program we use :




PYTHONPATH=/tools/python2.2.debug/lib/python2.2:/tools/python2.2.debug/lib/python2.2/lib-tk:/tools/xmlproc0.70:/tools/doctemplate2.2.1:/tools/python2.2.debug/lib/python2.2/plat-aix4:/tools/python2.2.debug/lib/python2.2/lib-dynload:/tools/python2.2.debug/lib/python2.2/site-packages

test program :
-------------------

#include <iostream.h>
#include <Python.h>

int main(int i__argc,char* i__argv[])
{

        Py_Initialize();

        cout << endl << "CALL of PyImport_ImportModule with argument "
<< getenv("NAME_MODULE")
<< endl;

        PyObject * l__obj =
PyImport_ImportModule(getenv("NAME_MODULE"));

        if (l__obj == NULL)
          cout << "importation of module " << getenv("NAME_MODULE") << "
failed !" << endl;

        return 1;
}


We ran this test program for different values of $NAME_MODULE.

$NAME_MODULE      |    result?
-------------------------------------------------------------
base64          |    KO (Segmentation fault) at the call of
PyImport_ImportModule
os                   |    OK
strop              |    KO (Segmentation fault) at the call of
PyImport_ImportModule
string             |    KO (Segmentation fault) at the call of
PyImport_ImportModule

What do we see with dbx (Python 2.2 is compiled in debug mode)?
-------------------------------------
The last instructions in the stack are :

stropmodule.split_whitespace(s = "strop", len = 806723600, maxsplit =
806727672), line 80 in
"stropmodule.c"
initstrop(), line 1221 in "stropmodule.c"
_PyImport_LoadDynamicModule(0x2ff1d2b0, 0x2ff1cdc0, 0xf0004d40), line 53
in "importdl.c"

with 0x2ff1d2b0 = "strop"
        0x2ff1cdc0 =
"/tools/python2.2.debug/lib/python2.2/lib-dynload/strop.so"
