gnugo-3.7.9 --replay white 33990.sgf -o 33990-r379.sgf produces a broken sgf file

[alain]

A (bad) game played on CGOS.
sgfc and cgoban say the 33990.sgf file is valid.

$ sgfc 33990.sgf
33990.sgf: OK

$ gnugo-3.7.9-ref --replay white 33990.sgf -o 33990-replay-379.sgf
$ sgfc 33990-replay-379.sgf

33990-replay-379.sgf: 5 error(s)

The original game was played with --capture-all-dead. If using this option during the replay, everything is ok.

To clarify the problem, part of the output file looks like

C[GNU Go plays Pass (0.00) - Game move J2 (0.00)]CR[``];B[hb]
;W[hh]C[GNU Go plays Pass (0.00) - Game move H2 (0.00)]CR[``]
;B[ca];W[di]C[GNU Go plays Pass (0.00) - Game move D1 (0.00)]
CR[``];B[db];W[eh]C[GNU Go plays Pass (0.00) - Game move E2 (0.00)]
CR[``];B[fc];W[]C[GNU Go plays the same move Pass (0.00)];B[ga]

where the CR properties are invalid.
