Memory leak in Mutex

Added by stass (Stanislav Sedov) almost 10 years ago. Updated almost 10 years ago.

Status:
Closed
Priority:
Normal
Target version:
-
ruby -v:
ruby 2.0.0dev (2012-09-20 trunk 36995) [x86_64-freebsd10.0]
Backport:
[ruby-core:47619]

Description

=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.
