core dump during test_array for Python.2.0b1

[Art Haas]

Hi.

I'm trying out the latest and greatest version, and get a core dump
when running the `test_array' test.

I'm running on Linux, i686 (Redhat-6.2).

Here's a little info courtesy of gdb.

$3 = {ob_refcnt = 0, ob_type = 0x4019a960, ob_size = 15, 
  ob_item = 0x816b730 "ccThe quick abc\b\030", ob_descr = 0x40199760}

The pointer isn't null, but it looks like things die in the free() call.

The array module is built as a shared module, if this makes a difference.

Anyone else seeing this???
