Summary: PF: distinct-values triggers assertion
Initial Comment:
[query written by an ADT student]
The use of fn:distinct-values in the following query results in an assertion
failed, only when the algebra backend is used (hence, not in MPS):
$ echo 'for $fname in
distinct-values(doc("people")/people/person/leisure_activities/*)
order by $fname
return <activity> { $fname/text() } </activity>' | pf -A
pf: /ufs/zhang/monet/stable/pathfinder/compiler/mil/milgen.brg:7875: do_reduce:
Assertion `!(type_of (((p)->child[0]), p->sem.ii.item) & ~0x0000F000)' failed.
Aborted

Please check & comment whether this is indeed the desired/expected error
message.

Message:
The query should always generate an error.
Avoided the assertion for this query in the CVS Head -- back-porting is
not possible due to usage of new error type.
