The following code cause a segmation fault:

<?php

$lines = 0;

$fp = fopen("test.txt", "r");

while ($line = fgets($fp, 128)) {

	$line = str_replace("with", "without", $line);
//	$line = ereg_replace("with", "without", $line);
	$lines += 1;
	if (($lines % 100) == 0) {
		echo($lines . " - " . $line . "<BR>\n");
		flush();
	}
}

fclose($fp);

?>

The "text.txt" file was a file with more than 300 lines: "This is a line with a typo". 

When I use "str_replace", then the display only reach 200 (seg. fault), but no problem occurs if I use "ereg_replace".
