I did as suggested (and turned -DDEBUGP on, too). Basically, what is
happening here is that the "bad trade" evaluation is being triggered.
This adds -1.8 to the total score. So without this term Crafty 16.1
evaluates the position at about +0.2, or close to even.

Couple of comments:
1. I think the "bad trade" penalty should be broken out separately
in the output of the "score" command.
2. Penalizing White for this doesn't make much sense here. Bishop
+ a couple of extra pawns is often drawn.
