This was because I built it without --enable-gl .  So it crashes when you
run gl-surface-source or gl-surface-source with the xcb target on Xvfb
(presumably without gl capabilities).

gl-surface-source egl-surface-source are still consistently crashing with
--enable-gl .


I'm still curious why this is resulting in a crash:


    surface = cairo_gl_surface_create (device,
                                       CAIRO_CONTENT_COLOR_ALPHA,
                                       size, size);

    return surface;


https://cairographics.org/manual/cairo-Image-Surfaces.html#cairo-image-surface-create

"Returns

a pointer to the newly created surface. The caller owns the surface and
should call cairo_surface_destroy() when done with it.

This function always returns a valid pointer, but it will return a pointer
to a "nil" surface if an error such as out of memory occurs. You can use
cairo_surface_status() to check for this."

in test/cairo-test.c this seems to be hitting something like:

  if (cairo_surface_status (test_image) == CAIRO_STATUS_INVALID_STATUS)
      ret = CAIRO_TEST_CRASHED;
