Can you post the game?

I told Amir Ban some monthes ago about the bug of losing on time.
I found it in a game between Junior5 and Junior4.6(engine against engine)
1 minute per game+ 15 seconds per move.

It is rare but can happen because Junior5 feels a duty to finish the iteration
and does not look in the clock before finishing the iteration.

Another possibility is that Junior5 was in an infinite loop.
I do not know if an infinite loop  is possible in practical game but I found
that it is probably possible if I change the threshold parameter (I can never be
sure that a loop is infinite and not finite without knowing the source code).
