Indeed. But it's impossible to debug what you described, at least I
don't know how to do that, not without a recipe that can reliably
trigger the problem.

Conditional breakpoint where?
With these issues, the only way to find the bug is to step through the
offending code _before_ it produces the wrong values. So we need a
condition that happens at the beginning of that code, not where it
produces the final wrong results.
