[gecode-users] example problem

[Alejandro Arbelaez]

thanks a lot for your quickly answer, because I'm modifying some critical
parts of gecode to get some information during the propagation process and
it's very difficult to understand these problems (especially because on
linux, with gcc 4.1.3, I don't get the segmentation fault).

Best regards,
Alejandro
