Subject: Gandalf 6 UCI has serious bug: stops after 1 hour in infinite analysis!!

I didn't get any answer to yesterday message yet. I used about 10 hours to
investigate bug more. And my finding is : after 2^32 nodes Gandalf UCI stops
totally under Fritz as well as CP GUI! Note, that this can happen in 1 hour
with fast PC. Another good test position is this:

[D]2r5/2pR1pk1/p1P3p1/P2K4/5P1p/5P1P/8/8 w - -

As CP native I am not sure what happens after 2^32 nodes. Node counter goes to
0, but may be engine still runs. Note bug in latest Chess Partner interface:
after 2^31 (not 2^32) nodes nps goes insane .
