Summary: preceding-sibling failure
Initial Comment:
let $c := <a><t/><t/><p/><t><p/></t></a>
for $doc in $c//p
return $doc/preceding-sibling::*
causes the following error:
ERROR = !ERROR: PFll_child: both iter_bat and ctx_bat must have a dense head.
!ERROR: PFll_child: operation failed.
the same query, however, works fine as soon as we change "preceding-sibling" by
"following-sibling"

Fixed in CVS (XQuery_0-20 release branch):
ll_preceding relied on properties that ll_parent did not set completely in
all cases;
in case the result of ll_parent is as long at the input, i.e., each item
found a (per iter)
unique item, then the ll_parent result head (iter) should inherit the
properties of the input
iter_bat's tail.
Added test in
pathfinder/tests/BugTracker/Tests/preceding-sibling_failure.SF-1841747*

confirmed for default (i.e., `Mserver --debug=0`); however, it seems to
work fine with property checking enabled (i.e., `Mserver --debug=10`);
hence, it's most probably a property related issue --- investigating ...
