New submission from Terry J. Reedy:

In console: pcbuild/win32/python_d.exe -m test -j6
[393/395/1] test_fileio
Traceback (most recent call last):

Exception: Child error on test_fileio: Exit code 2147483651

In crash box: Debug assertion failed
line 56  _osfile(desfile) & FOPEN

By leaving box alone, all but about 4 tests finished.  When clicked on button, fileio message appeared. On previous run, click as soon as box appeared, and console window frooze much sooner, with just half of tests run.

There were also 'Python_d.exe has stopped working' messages, but same true with 3.4 tests, which finished.
