Comment 0 for bug 867171

When I try to load the page http://www.xqueryfunctions.com/xq/functx_fragment-from-uri.html the http module raises an error, and then zorba crashes at finish with the message "strings still in the pool".

The test looks like:
import module namespace http = "http://expath.org/ns/http-client";
variable $load-result;
$load-result := http:send-request(<http:request method="GET" href="http://www.xqueryfunctions.com/xq/functx_fragment-from-uri.html"/>);
$load-result

and the error message is (after I removed some try - catch in http-client.xq):
<?xml version="1.0" encoding="UTF-8"?>
