New Infinite Loop-5, 1e (notes on RDChess 3.23)

There were very strang losing/suicidal moves from RDChess 3.23 in three
games of five.
10.Qa4+?? (vs Dragon)
10... Nxe4? (vs Eeyore)
22... Rd1+?? (vs Tinker 4.47)

Yes, I know.
As I mentioned before already in this forum, I am not able to find this bug in RDChess. One possibility is RDChess uses a wrong move from the hash table, but I really do NOT know.
Sorry, Greetings Rudolf.

What about disabling hash tables.
You can see if Rdchess performs better without hash tables or when you use them only for better order of moves.
