New submission from Maxwell Bernstein <[email protected]>:
On a debug build, the following causes an abort:
import _io
_io.FileIO("foobar", opener=lambda name, flags: 1000000)
1000000 is not a valid fd. FileIO attempts to raise an IOError from errno, but
there is already an exception set when PyErr_SetFromErrno uses PyObject_Call to
create the exception.
