Komodo finally found it! The result is a bit unflattering mainly because it takes the program long to resolve a new move with PV search at high depths. Depth 43 is higher for Komodo than for Stockfish although surely in the past this difference was larger. My latest version of search.cpp for Stockfish MOD also can't reach high iterations here, but the actual depths at each iteration reached are higher I hope see below.
