That's inside the Qt library, and at a quick glance, the Q_ASSERT macro is
being used there, which as far as I understand does nothing when the
QT_NO_DEBUG macro is defined when building Qt.

I currently cannot reproduce with current master build on Debian testing
(libqt5core5a package at version 5.14.2+dfsg-6.).
So this might be related to the build flags that Gentoo is using for the Qt
libraries (which does not necessarily mean it's Gentoo's fault, but would
explain why I cannot reproduce on Debian).
I think I saw something similar when testing some Qt app against a
self-compiled Qt with debug information quite a while ago, don't remember
whether it was even LibreOffice....

Can you recheck whether it still happens with a current daily build of master,
available at [1]? You can install it in parallel as described at [2].
