I modified test flwor10.xq to be: declare namespace ext = "http://www.zorba-xquery.com/extensions";
variable $x := 0; (# ext:materialize #) { for $i in (1, 2, 3) let $y := { $x := $x + $i; () } return $x } ran it and got: Zorba error [zerr:ZXQP0002]: "false": assertion failed with the message: ClauseKind = materialize_clause; raised at /Users/pjl/src/flwor/zorba/repo/bug-1026250/zorba/src/compiler/codegen/plan_visitor.cpp:1028 The switch statement doesn't have a case for materialize_clause. Either it should, or it should never be the case that a materialize_clause should occur here. FYI: I modified the code on the branch to overload operator<< for ClauseKind -- makes it handy for debugging. -- https://code.launchpad.net/~zorba-coders/zorba/bug-1026250/+merge/138044 Your team Zorba Coders is subscribed to branch lp:zorba. -- Mailing list: https://launchpad.net/~zorba-coders Post to : zorba-coders@lists.launchpad.net Unsubscribe : https://launchpad.net/~zorba-coders More help : https://help.launchpad.net/ListHelp
