[Qt-interest] QT XmlPatterns crash

[Sujesh Babu N]

Hi,
I noticed a crash with xmlpatterns with latest code in QT repository.
( One of the application we develop , uses qt components and v1.1 of
the same need qt 4.7.4 , so i am using the latest from repository)

To reproduce the problem , compile latest qt from
http://www.qt.gitorious.org/qt/qt/commits/4.7  using Visual Studio
2010 or MinGW  (64bit) in windows ( i used windows 7)
then run ,  xmlpatterns m1.xsl m1.xml   ( test files m1.xml and m1.xsl
attached in this email) , then xmlpatterns crashes( crash log can be
found in attachment list (crashlog.txt))

Same test scenario is working fine in qt 4.7.2 and 4.7.3 in Visual
Studio and MinGW environments.

Should i create a bug in QT bug tracker or wait till 4.7.4 out to do the same ?

regards

PS : test xml/xsl's are taken from article
