Issue #9652 has been updated by Eric Wong. Thanks all, committed as r45364 Sorry my original patch set the ivar on the wrong object :x But fortunately I was able to reproduce the GC error and test for it. ---------------------------------------- Bug #9652: Marshal doesn't dump/load Time#zone correctly with too many time object https://bugs.ruby-lang.org/issues/9652#change-45871 * Author: Cantin Xu * Status: Closed * Priority: Normal * Assignee: * Category: core * Target version: current: 2.2.0 * ruby -v: ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0] * Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN ---------------------------------------- Hi, there I wrote a script to test Marshal dump/load with many time object ( see attachment ). basic idea is: 1) A is container of time, it contains 100,000 time instance (all Time.now). 2) dump/load A by using Marshal, expected behavior is all the time zone must same as Time.now.zone but I get different things or unreadable code in some Time instance by calling time.zone. mostly it's "UTF-8'. env: Mac 10.9.2, ruby: ruby 2.1.1-p76 PS: it's fine while A contain 10,000 time instance ---Files-------------------------------- timezone_test.rb (409 Bytes) -- https://bugs.ruby-lang.org/
