driCreateContextAttribs() emits an error if bit __DRI_CTX_FLAG_ROBUST_BUFFER_ACCESS is set for an ES context. But, EGL_EXT_create_context_robustness and EGL 1.5 both allow creation of robust ES contexts. One requests a robust ES context by setting the EGL_CONTEXT_OPENGL_ROBUST_ACCESS *attribute*, which Mesa's EGL layer translates into the __DRI_CTX_FLAG_ROBUST_BUFFER_ACCESS *bit*.
