Although the backtrace after the segfault does not show other functions between vtkOpenGLRenderWindow::OpenGLInit and vbo_exec_EvalCoord1fv I am able to set a breakpoint at vtkOpenGLRenderWindow::OpenGLInit and step through the program. I can see the execution moving through mesa functions. I'm only showing the breakpoint and the output after each "step" where gdb gives me a new "function () at file:line"
Breakpoint 1, vtkOpenGLRenderWindow::OpenGLInit (this=0x69b7e0)

I hope this is useful somehow.
