I have a crash when importing my boost python
extension. With the following configuration.
- python 2.7
- boost 1.45
- vacpp 11.1
- AIX 5.3
The problem can be reproduced with boost python examples as well.
Currently I have a working solution using python 2.54.
This is what the core dump shows:
boost::python::incref<_object>,
boost::python::api::object::object,
boost::python::api::slice_nil::slice_nil,
__init__0,
...2femos_5fesuite_2femos_5fdata_2fsms_2fecflow_5f2_5f0_5f22_2fPyext_2fsrc_2fBoostPythonUtil_2ecpp,
FP=fffffffffff3d00
.initialize_one_library__Fi,
.initialize_libs__FPii,
.load_libs__FPcPFv_iT1,
.loadAndInit,
.dlopen,
._PyImport_GetDynLoadFunc,
._PyImport_LoadDynamicModule,
.initimp,
.initimp,
.initimp,
.initimp,
.PyImport_ImportModuleLevel,
.fgets,
Here is the code associated with the stack dump above;
----------------------------------------------------------------
template <class T>
inline T* incref(T* p)
{
Py_INCREF(python::upcast<PyObject>(p));
return p;
}
------------------------------------------------------------
inline object::object()
: object_base(python::incref(Py_None))
{}
------------------------------------------------------------
#ifndef SLICE_NIL_DWA2002620_HPP
# define SLICE_NIL_DWA2002620_HPP
# include <boost/python/detail/prefix.hpp>
# include <boost/python/object_core.hpp>
namespace boost { namespace python { namespace api {
class slice_nil : public object
{
public:
slice_nil() : object() {}
};
# ifndef _ // Watch out for GNU gettext users, who #define _(x)
static const slice_nil _ = slice_nil();
# endif
===========================================
Total view shows that p(i.e Py_None) is NULL/0
It appears that when the static slice_nil is created at
module import time. We end up with Py_None being
NULL/0.
Could this be a problem with the way the python 2.7 was
installed/set up.
Any help would be greatly appreciated.
Best regards,
Ta,
Avi
