hm, I don't know much about the lifetime requirements of these device
contexts, but at first glance it seems independent of the GL context
(there is a CreateDC call in the TextWIN32Backend c'tor).

the singletons register a cleanup function that gets called from
osgExit, calling it manually will likely result in a double free when
osgExit runs at a later point.
Can you try changing the line:
OSG_SINGLETON_INST(TextFaceFactoryBase, addPostFactoryExitFunction)
to
OSG_SINGLETON_INST(TextFaceFactoryBase, addPreFactoryExitFunction)
in Source/System/Text/OSGTextFaceFactory.cpp?
It seems like a bug to keep this around until after the
FieldContainerFactory is destroyed given that it holds various things in
caches.
Cheers,
Carsten
