    Display list corruption when list created in shared library

    This has me scratching my head a bit ...
    In my application there are a number of contexts which share display lists. This all works fine but ... when I create a display list in a shared library
    (loaded as a plugin by the application) then delete it, create a new one &c, the application segfaults
    when it attempts to draw the display list, usually after the first create/destroy/create cycle but not
    always, and usually when attempting to draw the display list in a context other than the one in which it was created.

    Tricky, are you sure you have an active context when you create? Are you checking for errors? You're not mulithreaded are you? That would raise the spectre of synchronization etc.

    Of course it could be a driver problem too.
