The problem in 51355 is that escape analysis decided that the dictionary variable was captured by reference instead of by value. We want dictionaries to always be captured by value. Escape analysis was confused because it saw what it thought was a reassignment of the dictionary variable. In fact, it was the only assignment, it just wasn't marked as the defining assignment. Fix that. Add an assert to make sure this stays true.
