Hi,
The enclosed example triggers stackoverflow-errror.
I was wandering if it is a bug.
The example should collect all ID-attribute-values of the containerElements, which are iterative-recursive.
The $go($go, .) construction is inspired from Leo Wörtelers xq-modules: https://github.com/LeoWoerteler/xq-modules.
Cheers,
Rob Stapper

yes, this definitely is a bug in the compiler. The function item
$go is inlined even though it is (kind of) recursive, which leads to an infinite loop. I already have a fix for this lying around but I didn't finalize it yet because I didn't think you could produce these loops in XQuery.
I raised an issue on GitHub [1] and will submit the fix as soon as possible. Thank you for reporting it!Quoted text · Rob Stapper · 2 lines

Christian merged my pull request [2] and uploaded a new snapshot [3], could you try that and see if the problem is fixed?
