[Bug-gnubg] Differences in SGF parsing between gnubg 0.14 and 0.90

[dankwart.plattner]

Hi,

I have some old sgf files created with gnubg 0.14 mingw. I recently 
opened both with GNUBG 0.90 (my version:  0.90-mingw 20100220) and with 
a text editor (see attached zip file).

The first line (for the first game) reads:
(;FF[4]GM[6]CA[UTF-8]AP[GNU 
Backgammon:0.14-mingw]MI[length:5][game:0][ws:0][bs:0][wtime:0][btime:0][wtimeouts:0][btimeouts:0]PW[aakjaer]PB[You]RU[Crawford:Jacoby]RE[W+2]GS[M:25 
22 29 29 0 1 0 1 0 2 0 0 29 25 0.004441 0.000644 0.675724 0.097980][C:30 
4 1 1 1 0 0 1 2 0 0 0 0 1 1 0 0 0 0 0 0.182533 0.026467 0.000000

0.000000 0.000000 0.000000 0.000000 0.000000 0.040819 0.002980 0.000000 
0.000000 0.000000 0.000000 0.000000 0.000000][D:0 1 4 4 23 22 1 0 1 2 
-0.568007 -0.046760 -1.232366 -0.181898]

The interesting numbers are the 4 at the end of the GS[...] portion 
which relate to checker play: 0.004441 0.000644 0.675724 0.097980. In 
the GNUBG's analysis window (see attached jpg file) they show as -0,005 
(-0,068) and -0,676 (-10,153), which is quite different for 3 of the 
numbers.

The same kind of differences show in the rest of the games, and in other 
matches, as well, and seem to occur systematically. Needless to say, the 
obscure all values dependent on these numbers as well.
In general, GNUBG 0.90 reads what's in the sgf file only if the sgf file 
is made with GNUBG 0.90. If the sgf file ist made with GNUBG 0.14, GNUBG 
0.90 reads something different.

Is there an explanation? Is this a bug? Any thoughts on this? Any 
possibility to avoid this behaviour?
