XMLpatterns craches while processing simple XQuery on big XML file

I send you the simple query that extracts coordinates of parcels from xml-files. These xml-files are used in Russia in cadastre. I was using both xmlpatterns.exe and QtXmlPatterns4.dll through simple program. Everything worked Ok, but once I needed to execute my query on a big xml-file and I found that xmlpatterns crashes trying to process this big file.
I checked execution of my query in different XQuery processor. I tried to use Altova XMLSpy. This program processed my query on that big xml file without problem.
That time I was using SDK 1.1.2 and Qt 4.7.3 with mingw
I decided to update to SDK 1.1.3 and Qt 4.7.4 but problem persists.
I attach my query and two xml file. Small.xml is processed Ok, but Big.xml makes xmlpatterns crash.
Both files are processed Ok in Altova XMLSpy.
