The first assert

  assert (locale_path_ptr != NULL);

is not removed for some reason.  This looks like a GCC bug to me.  GCC
is generally able to determine that addresses on the stack cannot be
null.

I suppose we can remove the assert.

The one after __argz_add_sep does not get optimized out, either, but
that's correct, and I think the assert is valid.

Thanks,
Florian
