This could have something to do with the free list used in mxDateTime.
Try compiling mxDateTime without free list support (edit mxDateTime.c
near the top and disable the two defines).

If that helps, you're set. The bus error sounds very much
like a compiler optimization bug to me. I've never heard of any
bug report related to _Py_NewReference().
