Comment # 16 on bug 81680 from Michel Dänzer

Okay, looks like it's crashing in st_texture_release_all_sampler_views(),
specifically on this line of pipe_sampler_view_reference():

      old_view->context->sampler_view_destroy(old_view->context, old_view);

Maybe old_view->context is no longer a valid context.

That looks like a different crash. Or maybe this is actually part of the normal
operation of the JavaScript JIT; what happens if you run 'continue' when this
happens?
