Summary: Typeswitch statement with "$var as" clauses causes crash
Initial Comment:
The following function crashes Sedna when it gets into the second (element())
branch:
declare function local:get-text ($n as node ()) as xs:string {
typeswitch ($n)
case $t as text () return string ($t)
case $e as element() return (
let $child-text := (for $c in $e/child::node() return local:get-text($c))
return
if (name ($e) = "link") then (
if (exists ($e/child::node()))
then string-join ($child-text, "")
else $e/@label
) else
string-join ($child-text, "")
)
default return "unknown"
};
If I rewrite it using a simplified typeswitch (without "var as" clauses), it
works just fine.
