Bug in GNUchess 5 engine

[Gert Winderlich]

Hello programmers,

 

I found a bug in GNUchess 5.0 engine

Winboard 4.2.6 + GNUChess v5.02+

running on PC, Win2000

 

- Mode > Edit Position

- right click > Clear Board

- set black king to e8

- set white king to e6

- set white pawn to d6

- Mode > Edit Game

- move Kf6

- Mode > Machine black

after 9 seconds a Windows message box pops up:

Fatal error

Error: first chess program (GNUChes5 xboard) exites unexpectedly.

- after clicking OK, the program crashs

- there are no problems in GNUChess 4.0 when doing the same actions

 

Can you reproduce this?

 

Regards,

Gert Winderlich
