I found four problems, all similar. Here's a C lesson for you:

	if (!(job_resrcs_ptr->node_bitmap = bit_copy(bitmap)))
		fatal("bit_copy malloc failure");

Is equivalent to:

	job_resrcs_ptr->node_bitmap = bit_copy(bitmap);
	if (!job_resrcs_ptr->node_bitmap)
		fatal("bit_copy malloc failure");

It is just compressed to save some space and perhaps make the logic more clear. So rather than remove the 2 lines in the first example complete, it needed to be change to:

	job_resrcs_ptr->node_bitmap = bit_copy(bitmap);
