The code in question in Parted:

                if (!add_partition (disk, part)) {
                        ok[i - 1] = 0;
                        errnums[i - 1] = errno;
                }

        char *bad_part_list = NULL;

        for (i = 1; i <= lpn; i++) {

                        continue;
                if (bad_part_list == NULL) {

With the patch below, I strace’d ‘parted’, which gives:

So I threw more virtual RAM at it:
