Let me take the silence as a suggestion that I have provided
the wrong information...

I am calling the following code from my frame constructor:
m_buttonBar = new wxToolBar(this, -1, wxDefaultPosition, wxDefaultSize);

This causes a crash under wxX11 (but works under wxGTK and Win32).
Am I doing something obvious wrong here?

It is acting perhaps like it's trying to access the window before
it's been created?  I'm grasping here.
