// Test for http://code.google.com/p/v8/issues/detail?id=386
|
|
// This test creates enough properties in A so that adding i as
|
|
// a constant function, in the first call to the constructor, leaves
|
|
// the object's map in the fast case and adds a constant function map
|
|
// transition.
|
|
// Adding i in the second call to the constructor creates a real property,
|
|
// and simultaneously converts the object from fast case to slow case
|
|
// and changes i from a map transition to a real property. There was
|
|
// a flaw in the code that handled this combination of events.
