Hi Tord,

It seems I have found a bug in Glaurung 1.02.
Glaurung crashed here after it reached depth 60 before
it could make the last move for a 3 time repetition.
(Max depth problem?)
I have played already 118 games with it at 40/15min
and this was the first time a problem occured.
(I have also a Polyglot log in case you need it)

This is strange. Glaurung 1.0.2 has been very thoroughly tested, and I haven't seen anyone report any crashes until now. I'll have a look at it and see what I can do.

(I have also a Polyglot log in case you need it)

Yes, that would be useful. Please send me the log.

Thanks for the bug report!

Hi again,

I have looked into the Polyglot log and it seems Glaurung fell into a loop
for the two only possible moves Kh8 and Kh6.
After seldepth 60 I counted the incredible number of 29.962! lines
of such info: (I will send the log after I have cut it from the other games)

Yes, this is a well known output bug (fixed in Glaurung CCT8). It creates a very annoying amount of debug output, but is otherwise harmless. I am fairly sure it was not this bug that caused the crash.
