Assuming that Arend is correct (though he didn't give enough details
to confirm it independently) there must be another problem because
D305 is this pattern:

Pattern D305

??.?       attach
..X.
O.*.
....

:8,-,value(75)

It is clear that if this pattern is matched, none of the
empty intersections is the location of a capture, so this
can't be the whole story.

It might be easier to debug the patch paul_3_13.8a than the
version paul_3_13.8b which went into the CVS.
