Indeed. I'll take a look at it.

Indeed. I'll take a look at it.

Thanks.
I was hoping to include it in my Amateur Division 7, which is starting on Saturday.

That would be great
The bug should be fixed in version 0.39.2

Works well now. Thanks, Werner.

Can we combine 0.39 and 0.39.2 results? Or have you made changes affecting strength, too?

[Werner Taelemans]

Can we combine 0.39 and 0.39.2 results?

No problem, they have the same strength. Also, Arena doesn't trigger this bug.

I haven't tested v0.39.x yet but thought I'd report a drastic eval anomaly exhibited by v0.38:

The last 50+ moves are 0.00 according to Galjoen's opponent and this eval is also confirmed by SF9. Yet Galjoen persisted with an eval between +250 and +300 cp. Perhaps its passed-pawn bonus is way too high?

[Werner Taelemans]

Perhaps its passed-pawn bonus is way too high?

That's possible. But the eval of 0.39 looks better. When I compare the first 10 plies in the position right after the last pawn capture:
[D]8/Pb6/8/2Bp4/3Pp2R/4K3/7r/6k1 w - - 1 137

between SF-9 and Galjoen 0.39.2:
