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.
