Subject: [ruby-dev:43628] [Ruby 1.9 - Bug #4829][Open] test_thread.rb reposet "malloc: ***  pointer being freed was not allocated" on Mac OS X


Issue #4829 has been reported by Tomoyuki Chikanaga.

----------------------------------------
Bug #4829: test_thread.rb reposet "malloc: ***  pointer being freed was not allocated" on Mac OS X
http://redmine.ruby-lang.org/issues/4829

Author: Tomoyuki Chikanaga
Status: Open
Priority: Normal
Assignee: 
Category: core
Target version: 1.9.3
ruby -v: ruby 1.9.3dev (2011-06-01 trunk 31885) [x86_64-darwin10.7.0]


r31885 以降の trunk で make test-all TESTS="-vq ruby/test_thread.rb" を実行すると以下のように
free に不正なポインタを渡したというメッセージが出て Failure になります。

  1) Failure:
test_thread_instance_variable(TestThread) [/Users/nagachika/opt/ruby-trunk/src/ruby/test/ruby/test_thread.rb:583]:
[ruby-core:35192].
<[]> expected but was
<["ruby-trunk(11715,0x7fff70e5eca0) malloc: *** error for object 0x1018155e0: pointer being freed was not allocated",
 "*** set a breakpoint in malloc_error_break to debug"]>.

しかし r31885 は rubygems のマージで C のコードの変更はないため、
もともとあった問題が表面化したのだと思います。
