Thanks for the report. However, I don't think the backtrace is helpful
here. Could you please rebuild xboard with debug symbols enabled ?  For
example: (or I can provide the package if needed)

 apt-get source xboard
 cd xboard-4.7.2
 DEB_BUILD_OPTIONS=nostrip dpkg-buildpackage -us -uc

And then try again to crash xboard to get a more verbose backtrace.

Also, it would help if you could indicate a way to reproduce the
bug. When exactly does it crash ? Does it only happen with your chess
program ? Would it be possible to download it somewhere ?

Thanks,
Vincent
