Result:      main cbmc-cbmc-6.6.0/src/util/merge_irep.cpp:186:10: error: Reference to local variable returned. [returnReference]
Explanation: `entry` is a local std::pair<iterator,bool> returned by irep_store.insert(). `*entry.first` dereferences a set iterator, which yields a reference to an element owned by the container, not to the local `entry`. Returning it is valid, so the returnReference warning was a false positive. The PR makes lifetime tracking stop at `x.a` when it is dereferenced with unary `*`. That is exactly this `*entry.first` pattern (#11168), so removing the warning is correct.
