New submission from Alexey Izbyshev <izbys...@ispras.ru>:
Demo:
>>> os.execve('', ['a'], {})
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [WinError 0] The operation completed successfully: ''
The reason is that path_error() used throughout os module always uses
GetLastError() on Windows, but some functions are implemented via CRT calls
which report errors via errno. It seems that commit 292c83554 caused this issue.
