#version: dbae081(https://github.com/WebKit/WebKit-http/commit/dbae081ad7e22d9ab61edf2f337f6c2bb593c7f8) #Testcase: a = { get p() {print('get');}, p: 2, set p(b) {print('set');} }; a.p = 0; print('a.p:', a.p)； #Command: ./webkit/WebKitBuild/Release/bin/jsc testcase.js #Output: a.p: 0 #Expected output: set a.p: undefined #Description: When executing this test case, other engines (such as v8, SpiderMonkey, chakra, etc.) seem to call the 'get' method defined in the 'a' object and output the value of 'a.p' as 'undefined', but JavascriptCore changed the value of 'a.p' to 0. Maybe this is a bug of JavascriptCore.
