Make cumulative exceptions appear in the trace

[AltGr]

At the moment, the compiler will chose arbitrarily which one applies when two active exceptions (or more) return the same result (see 9ef8625).

It might be an issue in some cases to not document all of the applying exceptions in the trace.

This might be implemented by just tweaking the log messages, but in any case it means that we need to add a check that exception B applies after A was found to apply.
