VTK upgrade breaks the VegaFEM example with segfault
The segmentation fault happens in vtkOpenGLRenderWindow::GetColorBufferSizes, specifically when this function calls:
glGetFramebufferAttachmentParameteriv(GL_DRAW_FRAMEBUFFER,
attachment,
GL_FRAMEBUFFER_ATTACHMENT_RED_SIZE, &size);
here. This seems to be happening in Linux, can't be reproduced in Mac OSX.
