Summary: [PF] Alignment error for batbat_dbl_mul
Initial Comment:
(mps-version)
The attached query fails with
ERROR = !ERROR: batbat_dbl_mul: BATs l & r must be void-headed and head-aligned.
!ERROR: batbat_dbl_mul: operation failed.
if you change the "$p5*$pw5" into "$p5+$pw5", then the error message changes to
ERROR = !ERROR: batbat_dbl_add: BATs l & r must be void-headed and head-aligned.
!ERROR: batbat_dbl_add: operation failed.
so the problem lies in this neighbourhood.

A fix is checked into the stable branch that fixes both bugs #1887055 and
#1886994 (propagation is still pending).

1.) I cannot follow the 26000 lines of MIL code.
2.) I cannot follow the 150 lines of XQuery (as it is not indented
properly to recognize the nesting).
3.) I have no clue what the query does.
After looking at it for an hour I give up with absolutely no clue.
Maurice if you want to have this solved either use the algebra version or
come up with a smaller example (< 20 lines of XQuery).

Jan,
could you please have a quick look, whether this one rings a bell with
you?
Feel free to re-/un-assign in case it's not "your business"...
Thanks!
Stefan

Ok, property checking does not help --- in fact, [*]() is called with two
BAT of different length; hence, the bug is probably somewhere in the
pathfinder-generated MIL code, or in the XQuery translation in general...

Maurice,
did/could you by any chance try, whether it works better with property
checking enabled, i.e., when starting Mserver with "--debug=10"?
