[ruby-core:44411] [ruby-trunk - Bug #6246][Assigned] 1.9.3-p125 intermittent segfault

From: "mame (Yusuke Endoh)" <mame@...>
Date: 2012-04-17 12:00:36 UTC
List: ruby-core #44411
Issue #6246 has been updated by mame (Yusuke Endoh).

Status changed from Open to Assigned
Assignee set to authorNari (Narihiro Nakamura)

Hello,

Perhaps I could reproduce this issue with small example:

  class Foo
    def Foo.shutdown(*args)
      p Bar.inspect.size
    end
    Bar = (0..300).map do |x|
      x = x.to_s
      ObjectSpace.define_finalizer(x, Foo.method(:shutdown))
      x
    end
  end

This code causes segfault in my system.
The number (300) may vary depending on a system.


This looks like a bug of GC finalizer.
A finalizer invoked at process termination, seems to refer
GC'ed object, which lead to segfault.  I guess.

In fact, the "logging" gem, which is included in OP's trace,
seems to use define_finalizer as a substitute for at_exit.

Nari, please check it.

ruby -v: ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-linux]


I've seen this behavior in 1.9.3p0 and 1.9.3p125

Intermittently, a rails 3.2 rake task will break while compiling assets - about 1 in 10 runs will segfault. Our code is 10K's of lines of proprietary code. I am working on a simplified version you can use.

RAILS_ENV=new_staging bundle exec rake assets:precompile --trace
