The code is short. The same php script is being included in the page
which is displaying differently and the page which is causing the
apache segfault.
if (empty($ID)){
$ID='1';
}
$today = date("Ymd");
$conn = mysql_connect ([snip]);
if ($conn == false){
echo mysql_errno() . ": " . mysql_error() . "<BR>";
exit;
}
else {
$rtn = mysql_select_db ("[tablename]");
$sql = "select * from events where ID = ".$ID;
$result = mysql_query ($sql);
if ( ($row = mysql_fetch_row($result)) &&
($today<=$row[4]
) ){
//if ( $row =
mysql_fetch_
row($result)) {
switch ($fld){
case 2:
echo $row[2];
break;
case 5:
echo $row[5];
break;
case 6:
echo $row[6];
break;
case 7:
echo $row[7];
break;
default:
echo $row[1];
break;
}
}
}
By the way, the backtrace from the apache segfault is:
#0 0xb7e095cc in zend_hash_index_update_or_next_insert (ht=0xb7ea29c0, h=0,
pData=0xbfffdc60, nDataSize=12, pDest=0x0, flag=1)
at /home/sys/src/php-4.4.1/Zend/zend_hash.c:390
390 p = ht->arBuckets[nIndex];
(gdb) bt full
#0 0xb7e095cc in zend_hash_index_update_or_next_insert (ht=0xb7ea29c0, h=0,
pData=0xbfffdc60, nDataSize=12, pDest=0x0, flag=1)
at /home/sys/src/php-4.4.1/Zend/zend_hash.c:390
nIndex = 0
p = Variable "p" is not available.
(gdb)
That segfault backtrace is the same even if I compile php with the
--without-zend-memory-manager flag, and also when I disable all Zend
settings in php.ini.
Thanks,
Kristina
