2.6 and 3.0.1 used to disable the Microsoft CRT argument error handler: they return EINVAL, but newer versions don't, and should check their arguments before calling _spawnv.
FWIW, the checks are::
pathname != NULL
*pathname != '\0'
argv != NULL
*argv != NULL
**argv != '\0'
The first and third checks are guaranteed by the implementation, but the other three should be done in posix_spawnv().
And the other calls to the various nt.spawn* functions probably suffer the same problem.
