Package: xmille
Version: 2.0-13
Severity: important
I've had loads of crashes with xmille lately on i386, but not on
amd64. Finally it annoyed enough to take a look. The problem was
that onecard was doing Numseen[safety(bat)] with bat == C_INIT,
which safety did not handle.
This is easily fixed by making safety treat C_INIT the same way
as if STOP had been played. I've checked the other callers of
safety and none of them will use the C_INIT value so this is a
noop for them.
I've also found onecard's logic to be broken where
1) It tries to check S_RIGHT_WAY in Numseen, when Numseen is
indexed by card number, so it was checking C_100 instead.
2) It checks Numseen != 0, where it should really be Numseen == 0
since we're trying to determine whether the human can play a
safety followed immediately by another card to finish the game.
Attached patch should fix all these issues:
