Follow-up Comment #2, bug #45218 (project pspp):

This bug is happening in cmd_quick_cluster(). I can fix the issue by adding a
final else at the end of parser:

$ diff quick-cluster.c quick-cluster.c.original
<       else
<         {
<         lex_error (lexer, _("Invalid or unsupported subcommand"));
<         goto error;
<       }

Is there a reason not to do this? One reason is that it will break any SPSS
syntax that uses unsupported subcommands but that seems better than having
PSPP hang.
