Plan Serializer test fails due to HOF

[William Candillon]

The following queries:
declare namespace an = "http://www.zorba-xquery.com/annotations";
declare namespace o = "http://www.zorba-xquery.com/options/features";
declare option o:enable "hof";

declare %private variable $handlers := ();

declare %an:sequential function local:add($handler)
{
  $handlers := ($handlers, $handler);
};

declare function local:emit()
{
  for $h in $handlers
  return $h()
};
declare %an:sequential function local:test()
{
  local:add(local:handle#1);
  local:emit()
};

declare function local:handle($message)
{
  trace($message, "message")
};

local:test()

Fails with the plan serializer (segfault)

Assign to you for dispatching.

[Matthias Brantner (matthias-brantner)]

The problem doesn't seem to be related to plan serialization. Instead, it's a problem with higher-order functions which are still have experimental status.

[Nicolae Brinza (nbrinza)]

Fixed in the trunk. Added test as hof-101.xq
