Re: "exec" procedures don't handle the optional parameters unbounded situation?

Hi!

Sorry for the late reply.

What you’re seeing here is SIGABRT, not SIGSEGV, preceded by the message:

  A NULL argv[0] was passed through an exec system call.

That message comes from Gnulib’s ‘set_program_name’ [0], which is used
by all GNU Coreutils program, and which aborts when argv[0] is NULL.

Thanks,
