Bug #7041: Memory leak in Mutex
https://bugs.ruby-lang.org/issues/7041#change-29613

Author: stass (Stanislav Sedov)
Status: Assigned
Priority: Normal
Assignee: kosaki (Motohiro KOSAKI)
Category: YARV
Target version: 
ruby -v: ruby 2.0.0dev (2012-09-20 trunk 36995) [x86_64-freebsd10.0]


=begin
Ruby does not destroy pthread condattr structure after allocating and using it in pthread_thread.c:native_cond_initialize().
This causes a memory leak that can be demonstrated by the following snipplet:

  loop do
          Mutex.new
          GC.start
  end

The patch attached fixes it.
This happens on both 1.9 and head.
=end
