I encountered a stack overflow error with the following code, which is designed to return as many random numbers as the user requests.  BaseX's error suggested, "Try tail recursion?"  I think I am already using tail recursion.  Changing the $n variable from 1407 to 1406 or lower avoids the error.  Any number 1407 or higher triggers the error.

Thank you for any hints!

```

xquery version "3.1";

declare function local:get-random-numbers($how-many as xs:integer, $generator as map(*)) {
    if ($how-many ge 1) then
        (
            $generator?number,
            local:get-random-numbers($how-many - 1, $generator?next())
        )
    else
        ()
};

declare function local:get-random-numbers($how-many as xs:integer) {
    local:get-random-numbers($how-many, random-number-generator())
};

let $n := 1407
return
    local:get-random-numbers($n) => count()
