New issue 24209 by dpra...@chromium.org: Setter not called if added to prototype chain after IC has been generated http://code.google.com/p/chromium/issues/detail?id=24209 ( Migrated from http://buganizer/issue?id=1344252 ). kasperl on August 25 2008 23:00 (Assigned) Summary Setter not called if added to prototype chain after IC has been generated Component Chrome > Deprecated > V8 Engine Reporter kasperl Assignee kasperl CC chrome-bugs, v8-dev Type Bug Priority P2 Severity S2 In prod false Hotlist Cr__Rel_Future URLs affected <none> Notes See message from Geoffrey Garen from Apple: ---- Hello v8-ers! I've found a bug in v8's inline cache for "store to field:" A setter that is added to a prototype after the inline cache is recorded will not be called. Here's a testcase demonstrating the bug. It passes in Firefox 3 and Safari 3.1, but fails in v8. The basic problem is that the StoreField stub only verifies the target object's map, and not the maps in the target object's prototype chain. Should the StoreField stub consult the full prototype chain?
