Description
Built qtbase, qtshadertools and qtdeclarative on qt5@d3460c1f235cccc183148596d906350f0c2e06da with:
C:\qt_git\qtbase\configure.bat -opengl desktop -release -shared -ltcg -force-debug-info -nomake examples -nomake tests -prefix "C:\install"
Then aforementioned repos with:
C:\install\bin\qt-configure-module.bat C:\qt_git\qtdeclarative
Built the Fboitem example with:
C:\install\bin\qt-cmake-private.bat C:\qt_git\qtdeclarative\examples\quick\scenegraph\fboitem
When closing the Fboitem example window, a debug assertion is thrown. See screenshot.
This is the backtrace:
