Here is the code:
 
      $item_range  = $conn->results_array[0][0] . " - ";
      $item_range .= $conn->results_array[0][1]);
 
The ) is left over from a removed command. This mistake did not generate a parse error, but caused a segmentation fault in [Apache1.3.20 PHP 4.0.5] and hang task on [Apache 1.3.27 PHP 4.3.0 ]. The code is from an included file.
 
Trying to run the included file on it's own did generate the parse error.

On the OLD System: 
Apache/1.3.20 PHP/4.0.5 on HP-UX  B.10.20 A 9000/898 
it creates segmentaion fault without parse error.

On the NEW System:
Apache/1.3.27 PHP/4.3.0 on HP-UX  B.10.20 A 9000/898 
ita hangs task forever without any parse error.

OLD System ( segmentation fault )
