[basex-talk] Stack Overflow on 9.4.2

This `test.xq` file works on BaseX 9.4.1: ``` xquery version "3.1"; import module "urn:x-xspec:common:deep-equal" at "https://github.com/xspec/xspec/raw/c629869560ab2bce3a6199569917de70ede4bbc3/..."; let $r := Q{urn:x-xspec:common:deep-equal}deep-equal((), (), '') return element test { $r } ``` $ BaseX941/basex/bin/basex test.xq /tmp/BaseX941/basex/.basex: writing new configuration file. <test>true</test> But it fails on 9.4.2: $ BaseX942/basex/bin/basex test.xq /tmp/BaseX942/basex/.basex: writing new configuration file.
