Currently, the debug build of py3k fails in test_os.py with an assertion
in the C library inside the execv call.  This displays a dialogbox from the MSVC
Debug Library:

  Debug Assertion Failed!
  Program: c:\svn\py3k\PCBuild\python_d.exe
  File: execv.c
  Line: 44

  Expression: *argvector != NULL

  For information ....

The last line is the labels on three buttons that are displayed.


If I insert these statements into Modules\posixmodule.c:

	_CrtSetReportMode(_CRT_WARN, _CRTDBG_MODE_FILE);
	_CrtSetReportFile(_CRT_WARN, _CRTDBG_FILE_STDERR);
	_CrtSetReportMode(_CRT_ERROR, _CRTDBG_MODE_FILE);
	_CrtSetReportFile(_CRT_ERROR, _CRTDBG_FILE_STDERR);
	_CrtSetReportMode(_CRT_ASSERT, _CRTDBG_MODE_FILE);
	_CrtSetReportFile(_CRT_ASSERT, _CRTDBG_FILE_STDERR);

	_set_error_mode(_OUT_TO_STDERR);

and recompile and test then the dialog box looks like this:

  Die Anweisung in "0x10..." verweist auf Speicher in "0x00000000".  Der Vorgang
  "read" konnte nicht im Speciher durchgeführt werden.

  Klicken Sie auf "OK", um das programm zu beenden.
  Klicken Sie auf "Abbrechen", um das programm zu debuggen.

      OK Abbrechen

These messageboxes of course hang the tests on the windows build servers,
so probably it would be good if they could be disabled completely.
