Thanks for the report. Could you let us know the version of gnuchess in use. (Usually "gnuchess -v" or simply typing "gnuchess" in a terminal window will get this information). Also I assume this is the version packaged with a distro, can you let us know distro and version. I turned position in to epd r3kb1r/pppb1ppp/2n2n2/1P3q2/2P5/P3Pp1P/3P1PP1/R1BQKB1R b Kkq - bm 1; id 1; I'm unable to persuade the stock GNU Chess on Debian (6.2.5) to crash from this position with a few likely tries, it wants to play fxg2 when it is confident it will go on to improve its position. It can sometimes be hard to reproduce a specific crash from a game, as it can depend on time controls, or may be something outside of the program.
