  - bin/ext_transform_feedback-order elements triangles
  - bin/ext_transform_feedback-order elements points
  - bin/ext_transform_feedback-order elements lines
  - bin/ext_transform_feedback-order arrays triangles>
  - bin/ext_transform_feedback-order arrays points
  - bin/ext_transform_feedback-order arrays lines
  - arb_clear_buffer_object-formats (96-bit clears)

It's unclear whether the regression is caused by this particular commit or by the subsequent ASAN fix.
