Hi David,

Thanks for the response.  It ended up being how I declared the destructor for my derived class as J-S pointed out.  I was going down the path of when and if I needed to call releaseGLObjects() and nothing seemed to make a difference.  And I'm still a little unsure of when that method should be called (or even if it should).  But, fixing the destructor declaration stopped the crashes that I was seeing and I'm not explicitly calling releaseGLObjects() at all right now, on any object.

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)
