I found a position that breaks stockfish:
lichess.org/analysis/1k4rr/2b1p3/3pPp2/2pP1Pp1/1pP3Pp/pP5P/P7/4K3_w_-_-_0_1
Here the engine estimates a -15.8 in black's favor, but the game is a forced draw because there is no possible way for black to force a pawn breakthrough. White can keep moving his/her king for the rest of the game and can force a draw by the 75 move-rule (however, stockfish can't see this...). You can give black as many rooks and dark-squared bishops, but the game will still be a draw. White does not have to, and should not accept any of blacks' sacrifices, as that will lead to a possible win for black.
