Segmentation fault in Release mode for QTQuick Applications

For QML based applications, when compiled in release mode, Segmentation faults are observed. The same works fine in debug mode.

This has been observed specifically for the following components:

• Slider
• Video
• Label

the backtrace points to the following function:

void QmlUnitGenerator::generate(Document &output, const QV4::CompiledData::DependentTypesHasher &dependencyHasher)

The application specific QML files are interpreted correctly by the Interpreter. However the inbuilt QML components like the slider are not interpreted.

The compiler settings are as below:

 For Release mode

App.pro -spec /path/to/toolchain/usr/lib/qt5/mkspecs/linux-oe-g++ CONFIG+=qtquickcompiler && /usr/bin/make qmake_all

 For Debug mode

 App.pro -spec /path/to/toolchain/usr/lib/qt5/mkspecs/linux-oe-g++ CONFIG+=debug CONFIG+=qml_debug && /usr/bin/make qmake_all

 We are using the Yocto build system and release configuration.
