# PTAL! Calling with or without --ignition-staging is enough. Simple repro:

function foo(a) {
  return undefined + a;
}
foo();
%OptimizeFunctionOnNextCall(foo);
print(foo("2"));

# Difference:
- undefined2
+ NaN2

This seems to be a Crankshaft issues, but only if feedback is collected by Ignition.
