// Test case for Blue bug 379253

// Construct a json object string with the given number of properties

function GetJSONString(prefix, count)

{

var buffer = [];

for (var i = 0; i < count; i++) {

buffer.push('"' + prefix + i + '": true');

}

return "{ " + buffer.join(',') + " }";

}

var string1 = GetJSONString("prop", 100);

var string2 = GetJSONString("drop", 550);

// Create a JSON object with a 100 properties

var object1 = JSON.parse(string1);

// Clear reference to that object to make its properties eligible for collection

object1 = null;

// Parse a second JSON object, this time with a large number of properties

// This parse has a reviver passed in too to cause an enumeration to occur after parse

var k = 0;

var object2 = JSON.parse(string2, function(key, value) { return k++; });
