No locals.

Where line 327 is the last line here:

static void
_mesa_meta_begin(GLcontext *ctx, GLbitfield state)
{
   struct save_state *save = &ctx->Meta->Save;

   save->SavedState = state;

Actually ctx->Meta is NULL, like if _mesa_meta_init() has not been
called.

So if I break on _mesa_meta_begin and call _mesa_meta_init(ctx) manually
before continuing it works, kind of. No crashes, but there are some
other issues like not seeing anything unless I click in the window.
