Subject: what is the reasonable thing to with a segfault in php?
From: per@computer.org (Per Jessen)

Hi,

I've got a situation where a seemingly innocent statement produces a
segfault. I've tried reducing it to a single reproducable testcase, but
without success.  The problem is however solidly reproducable in the
context in which it occurs. 
I'm *certain* it is caused by a mistake in *my* code, but I feel it isn't
exactly appropriate for php to segfault because of a user error? 

Very briefly, this is an excerpt where the segfault occurs:

<h2><?php print $_SESSION['customers'][$customer]; ?></h2>
<?php

        $q="<longish SELECT query>";
        $result=mysql_query( $q ) or die("mysql:".mysql_error());

        $main_address=mysql_fetch_array( $result, MYSQL_ASSOC );

        $q="<longish SELECT query>";
        $result=mysql_query( $q ) or die(mysql_error());

        $billing_address=mysql_fetch_array( $result, MYSQL_ASSOC );

        $q="<longish SELECT query>";
        $result=mysql_query( $q ) or die(mysql_error());

        $technical_address=mysql_fetch_array( $result, MYSQL_ASSOC );

        $editmain=strcasecmp($_REQUEST['contact'],"main")==0;
        //$editbilling=strcasecmp($_REQUEST['contact'],"billing")==0;
        //$edittechnical=strcasecmp($_REQUEST['contact'],"technical")==0;

?>

If I uncomment either of the last 2 commented-out statements, I get a
segfault.
I'm using php 4.3.4 and apache 2.0.49 on linux 2.4.24. mysql is 4.0.15.
