Crash / freeze when playing chess

[David Erosa]

Binary package hint: gcompris

Playing level 2 of chess, I get random freezes and crashes. Seems to happen at random times, as I could not reproduce it every time.

Couldn't get a backtrace with gdb of a crash, but I backtraced a freeze (had to press ctrl+c in order to get it). Not very helpful:

(gdb) run
...
^C
Program received signal SIGINT, Interrupt.

Is this still a problem? The backtrace is not very helpful and there's not a lot to go on.

I get these freezes as well. Besides that, the computer opponent sometimes just stops playing but you can shut down the program normally.

To reproduce a freeze, just play the game where you have to checkmate the computer opponent with a king and two bishops. I never made it to the end because of the random freezes (chess training, level 3).

I started with --debug and redirected stderr (see attached file).

I can confirm the bug. When trying to use the chess part, gcompris immediately dies and disappears with no message to the command line.

I'm using amd64 karmic 2.6.31-17-generic SMP.

I also have the same issue.

I made some refactoring of the chess code, hopefuly this bug is no more.

Thanks, Bruno.

@all: does this ever occur for you in trusty or later?
