Stack sizes are annoying, calling is not an option IMHO.
Why the [censored] is he raising that absolutely harmless turn?

Stacking off

Well technically he's not raising the turn...

Honestly I probably call here and fold to any decent sized river bet. He could be doing this with a set but he could also be doing it with 22-99 or AT/KT/JT, etc. If he bets river though I'm outta there unless he gives me great odds.
