The material looks fine, but should it be black to move? With white to move,
Crafty showed something like +5 right away, but I didn't let it search very
much.

This is what I got from my modified Crafty:
15 209:38 -0.56 1. ... b5 2. h4 b4 3. Nce2 a5 4. Qd3
Qc7 5. h5 e5 6. hxg6 exd4 7. gxh7+
Kh8 8. Bxd4 Nxh7 9. Bxg7+ Kxg7 10.
Nd4
Black's score was dropping with each additional ply.
