A program which causes the analyzer to emit a spurious "Undefined or garbage
value returned to caller" warning

The attached program causes the analyzer to emit "Undefined or garbage value
returned to caller" for the return value of -cachedObjectWithNumber:. The
analyzer seems to skip over the execution of the while loop entirely, even
though by virtue of the enclosing if statement, it is guaranteed to execute at
least once.</pre>
