Thanks for the testing! But it looks like you have switched the white
h5-pawn into a black one in your test position! The correct position is:

5b1r/3bkp2/3ppp2/p6P/4PP2/1PNB4/1KP5/7R b - -

that is:
White: Kb2, Rh1, Bd3, Nc3, b3, c2, e4, f4, h5 (9 pieces)
Black: Ke7, Rh8, Bd7, Bf8, a5, d6, e6, f6, f7 (9 pieces)
Black to move

Will it take even longer for your engines now? I believe so :-)
