[Pyrex] PyArg_ParseTuple error "new style getargs ..."

[Drew Perttula]

pyrex 0.9.3.1; python 2.3.4.

It looks like an error in ParseTuple is getting reported in a later
line PyErr_Occurred line. This might be a cpython bug.

The SystemError seems to always occur on the first PyErr_Occurred
test, even if that line is quite innocent like in my example
below. Unfortunately, I cannot post the full source of my test.
