    Description

      in qopengl.cpp where the number of extensions are being asked for

      If the driver does not understand GL_NUM_EXTENSIONS it will leave numExtensions untouched.

      should make sure numExtensions is set to zero before calling glGetIntegerv in QGLExtensionMatcher::QGLExtensionMatcher (qtbase/src/gui/opengl/qopengl.cpp)
