 '''Update'''

 Haven't had time to really look into why this is happening on a Windows
 platform specifically, but I have found a fix:

 As per this thread: http://stackoverflow.com/a/39603464/988246 I changed
 the return of `wp_is_stream($path)` to single quotes rather than double:

 `return preg_match( '!^$wrappers_re://!', $path ) === 1;`

 The linked SO post suggests to me that the `$path` parameter of
 `wp_is_stream` is being passed null byte(s), and `preg_replace` with
 double quotes (`"`) is trying to parse them.
