Problem with dynamically linked extensions that use Numeric

[Alex]

Hi.  I have been writing an extension that uses the Numeric API.  Up
until now, I have just been building it straight into python, and it's
working fine.  However, I want to make it more widely available, so I
need to make shared objects from it.  The problem with that is that it
segfaults.  Here is a small piece of code that demonstrates the problem
I am having:

///////////////////////////////////////////////////////////////////////////////
#include "Python.h"
#include "arrayobject.h"

PyObject *test_array_test (PyObject *self, PyObject *args) {
  PyObject *t;
  int dimensions[2], i;
  
  if (!PyArg_ParseTuple (args, "")) {
    return NULL;
  }

  dimensions[0] = 10; dimensions[1] = 12;
  for (i=0; i < 20; i++) {
    printf ("testing\n");
    t = PyArray_FromDims (2, dimensions, PyArray_INT);
  }
  if (!t) {
    return NULL;
  }
  return t;
}

static PyMethodDef Test_ArrayMethods[] = {
  {"test", test_array_test, METH_VARARGS},
  {NULL, NULL}
};

void inittest_array () {
  (void) Py_InitModule ("test_array", Test_ArrayMethods);
}

///////////////////////////////////////////////////////////////////////////////

I compiled this using the 'make -f Makefile.pre.in boot' method.  Here
were the commands make generated:

[alex_c at puffin blast]$ make test_arraymodule.so
gcc  -I/scratch2/alex/include/python2.0/Numeric -g -O2 \
              -I/scratch2/alex/include/python2.0 \
              -I/scratch2/alex/include/python2.0 -DHAVE_CONFIG_H \
              -c ./test_arraymodule.c
gcc -shared  test_arraymodule.o  -o test_arraymodule.so

This code segfaults when it hits the line 
't = PyArray_FromDims (2, dimensions, PyArray_INT);'  But when it's
compiled directly in to python (i.e., I move the file into the Modules
directory of the python source, and add a corresponding entry in the
Setup file,) it works fine.

I'd be grateful for any ideas as to how to get this to work.
