Should I always call PyErr_Clear() when an exception occurs?

[Jaime Wyant]

I've found that the code below will crash if I don't have the
PyErr_Clear() function call. Should I always call PyErr_Clear()? The
error message I get has to do with garbage collection -->

Exception exceptions.ImportError: 'No module named badmodule' in 'garbage collec
tion' ignored
Fatal Python error: unexpected exception during garbage collection

/* Code that fails if PyErr_Clear() is removed */
#include "python.h"

int main()
{
PyObject *pName, *pModule;
int i;

Py_Initialize();
for (i = 0 ; i < 30; i++) {
// First, import the module
pName = PyString_FromString("badmodule");
pModule = PyImport_Import(pName);
Py_DECREF(pName);
if (!pModule)
{
fprintf(stderr, "couldn't import badmodule\n");
PyErr_Clear();
}
}

Py_Finalize();
}

/* End code */

Thanks,
