Bug in OliThink 5.21JA

Postby Guenther Simon » 06 Nov 2009, 19:29

Two weeks ago when starting a new RWBC rapid tournament I noticed that Jims
Olithink 5.21 version has some remarkable bug it seems?
(After changing to the 'normal' 5.21 version it never appeared again...)
I didn't save the WB pgn but the debugs and therefore the games below
are reconstrucred by the LGDEBPGN tool.

The bug itself manifests in x-raying the Q through opponents pieces
for a check on the opponents base row!

Hi Gabor,

This bug is not in the original Olithink 5.21 at least it never appeared here, thus I believe something went wrong when
Jim compiled his version?

Hi Günther,

I thought it was impossible to introduce a bug by compiling - unless Jim changed the source (?).

Jim wrote me a mail that this happened with Olithink, because of the MSVC compiler, no idea why.
Meanwhile he did a new compile with an Intel compiler and I will try to test it soon.
