[Bug-gnubg] Huge evaluation difference

Hi!

I just ran into a huge evaluation difference between XG and Gnu BG:

XGID=-B----CFC----A-------acbb-:1:1:1:16:0:0:0:5:10

I got dinged with a -0.684 error here while XG says it is a -0.0013
error to play 13/6.

Desktop version says it is:

    7. Cubeful 0-ply    13/6                         Eq.:  -2,264 ( -0,328)
       0,000 0,000 0,000 - 1,000 0,964 0,000
        0-ply cubeful prune [expert]

but still wildly off. Perhaps difficult to fix these kind of problems?

I also ran into a crash where sprintf is used instead of snprintf
causing a buffer overflow but I think I have reported that problem
before.

Best regards,
TP
