Hi:

Apparently  posix/tst-execvpe6.c is not valid anymore at least on linux
where  NULL argv is invalid. The kernel is way too nice and not killing the
process as it should but using an empty string instead.

so,

 char *args3[] = { NULL };
  if (run_script (fname2, args3))
    return 1;

is testing..

 char *args3[] = { "", NULL };
  if (run_script (fname2, args3))
    return 1;

instead.
