Bug Description

When I try to load the page http://www.xqueryfunctions.com/xq/functx_fragment-from-uri.html there are two errors (from libxml?) on the console, then Zorba crashes with an assertion failure.

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 output is:

I/O error : encoder error
xmlParseChunk: encoder error
zorba: /home/ceej/zo/src/src/store/naive/loader_fast.cpp:485: virtual store::Item_t zorba::simplestore::FastXmlLoader::loadXml(const zstring &, const zstring &, std::istream &): Assertion `thePathStack.empty()' failed.
zsh: abort (core dumped) bin/zorba -f -q /tmp/foo.xq

Matthias - could use some hints on this one. I know you're a bit familiar with the "strings in string pool" error - what code puts strings in the pool, and how are they supposed to be taken out?

The namespaces are put in string pool.
Probably some node items are not freed when throwing that error.

Disregard earlier comments about the string pool. The symptoms are now as described in the updated Description. Assigning to Nicolae.
