Details:

I'm adding code to PSPP v. 0.8.4 CLUSTER to show cluster membership (PRINT and
SAVE subcommands) and some of my test scripts fail to produce any output for
many seconds (normal run-time is < 1 sec; I've waited a minute or two). When I
add printf statements into kmeans_cluster() I see them when output is
produced, I don't see any output when PSPP hangs.

I then checked and these hangs occur in 0.8.4 (without any of my code). In the
attached file:

<pre>
* this works fine.
QUICK CLUSTER Married WorkF
  /CRITERIA=CLUSTERS(3).

* below causes hang in 0.8.4.
* with, or without the FOO.
QUICK CLUSTER Married WorkF
  /CRITERIA=CLUSTERS(3)
  /PRINT=INITIAL CLUSTER
  /FOO=BAR
  /SAVE=CLUSTER DISTANCE.
</pre>

After I've added my code to CLUSTER to parse PRINT and SAVE, the /FOO line
still hangs PSPP.

So, I conclude that there is a problem in how the subcommands of CLUSTER are
parsed that occurs before kmeans_cluster() sees the syntax.
