Looks like split of execve(2) syscall created bugs

[Matthew Dillon]

:Not quite. I've removed code which makes argv[0] == NULL
:a special case completely from kern_exec.c, but just haven't
:included relevant patch into this message since considered
:it obvious. If you want, I can probably make complete patch
:which will bring DF on par with FreeBSD, but I want to complete
:testing and commit my changes into FreeBSD repo first.

    There's no rush on it.  I've got the first half of the cleanup
    committed to DFly.  Nobody else is going to mess with it in DFly so
    feel free to finish it up any time.
