Hi Charles,
That was the problem. The destructor of my derived class was public. I
changed it to protected and to use a ref_ptr for the class and no more crashes.
I'm not sure I would have ever found this bug. I wasn't even looking in that
direction. So, thanks so much!
Glad I could he

Chuck,
I have had similar issues (with crashes in releaseGLObjects when views get

Chuck,
I have had similar issues (with crashes in releaseGLObjects when views get
destroyed) but can't actually recall what I did to fix them.
You could try calling viewer->releaseGLObjects() before you destroy the
view. (previous posts seem to suggest that this might be the right thing to
do)

Hi Charles,
When I referred to "destroy", what I'm doing is calling 'delete' on the classes
that contain the ref_ptrs. For instance, I call delete on my view class, and in the view
class' destructor, I (eventually) call delete on the drawables. So I'm in effect doing
what you're saying, with

Hi Charles,
My attempted process to close is that I (1) set a flag on a render thread to stop
calling viewer->frame (very similar to setDone(true)); (2) destroy the loaded
drawables and free their associated libraries; (3) destroy the view, and thus it's
associated camera and graphics context

Hi all,
I've been chasing an error in my code for many, many days that I'm hoping that
someone can help me track down. I'll try to explain my application as best I
can.
I'm using a composite viewer to load multiple views. In each view, I'm loading
a database scene (generally a TXP database)
