OK, so this is after the changes in question (commit da299bd98
"Allow users to set the precision of output statistics.")

It is a numeric variable whose value indicates how many "copies"
of the case should be considered to exist.  If there is no
weighting variable, then every case has a weight of 1.

It seems clear that you are right about this, but it is hard to
see how or why it would happen.  When there is a weighting
variable, the column in question is formatted using the weighting
variable's print format, but when there is no weighting variable,
this column is supposed to have an 8-column (not 5-column)
format.

Could you try running the following commands and show me the
output?

        SHOW WEIGHT.
        SHOW FORMAT.
