Thanks for setting up these checks, @youknowone. I usually only run tests in release mode, since all the tests take about 2 hours in release mode and would take even longer in debug mode. That's why I missed these overflow errors, which only show up in debug mode. I'll push out a fix soon.

Although there are benefits to running tests in debug mode (like finding those bugs), it just takes too long. It looks like the latest action was automatically cancelled after running for 6 hours. I've changed the tests to run in release mode.

Separating test groups to make simple and fast tests run on debug mode and others on release to take advantage of both overflow checking and optimized running can be another option
