There currently is a problem when compiling Qt with Visual Studio 2010 for 64-bit.
- Its optimizer causes trouble and crashes for the release builds and it is not supported
- in that configuration. See task http://bugreports.qt.nokia.com/browse/QTBUG-11445.
+ Its optimizer causes trouble and generates code that crashes for the release builds.
+ To avoid the crashes, You need to apply the hotfix in the following article
