Hi guys,
I am testing the current trunk version of OSG in my application (was
previously using v2.6.1) and I get a crash on shutdown when trying to
destroy a osgShadow::ShadowedScene. This only occurs when I have a
shadowTechnique set and is caused by destroying the shader program. I
am using OSG in Qt derived from a QGLWidget (yes I know I should
rather use the QWidget implementation, I am busy porting to that, but
this used to work fine in 2.6.1 so I thought I would flag it :)
I will see if this still happens when not using the GL Adapterwidget,
and report back.
