After using the apxs utility that comes with Apache to reconfigure and install PHP3 3.0.5 as a DSO, I attempted to access a script that was previously working on the same machine.  By eliminating a line of code at a time, It seems that the ereg_replace function in the code snippit below is causing the problem.  If I comment that line out, my script works just fine, if I leave it in, it causes Apache to report and Segmentation Fault and IE4 tells me that the server returned an invalid response.

<?
 $fp = fopen($dat_file_name, "r");
 $count = -1;
 while(!feof($fp)) {
   $data = explode(":", fgets($fp, 1024));
   // chomp
   $data[0] = chop($data[0]);
   $data[1] = ereg_replace( "\n", "", $data[1] );

   $tmp_array[$data[0]] = $data[1];

 }
 fclose($fp); 

?>
