It might be oracle bug, but here's the code that crashes my apache 1.3.12 and php 4.0.0: 

$link=ocilogon("what", "ever", "");
$q="select count(*)as C from CATEGORY where catpath like '|Produktkatalog|edin's category|%' and source=140";
$stmt=ociparse($link, $q);

Note that there is only a single (not escaped) quote after edin. It took the me some time to find what was wrong here and to cut the example to these 3 lines. Here's the backtrace:

Starting program: /data/gen/apache/bin/httpd -X -f /data/gen/apache/conf/httpd-genx.conf
