This changeto  data_readlines() fixes it for me.
This seems to work with files and with pipes,
but should be tested by the mantainer and the gurus.
Let me know if you need a diff.

static void data_readlines(void) {

	int i;
	char current_line[256];
	FILE *fp;

	fp = (inp_stdin) ? stdin : bb_xfopen(filename, "rt");

	for (i = 0; (feof(fp)==0) && (i <= MAXLINES); i++) {
		fgets(current_line, 256, fp);
		if(fp != stdin)
			bb_xferror(fp, filename);
		flines = xrealloc(flines, (i+1) * sizeof(char *));
		flines[i] = (char *) bb_xstrndup(current_line, (strlen(current_line) + 1) * sizeof(char));
	}
	num_flines = i - 2;

/* Reset variables for a new file */
