Bug #4820: EXC_CRASH (SIGABRT)

• Status: Rejected
• Assignee: sorah (Sorah Fukumori)
• Target version: 1.9.2
• ruby -v: 1.9.2-p180

[threadhead (Karl Smith)]

Ruby is crashing sporadically during rails development.

See crash logs: https://gist.github.com/982118

Have completely removed and reinstalled Xcode (3.2.6), ruby (via RPM), all gems. Still crashes.

[sorah (Sorah Fukumori)]

• Status changed from Open to Feedback

We need to the following additional information for fixing:

• What did you do to reproduce? what is "rails development"?
• we need raw output of ruby -v. Not only version number. (We need like platform str... like [x86_64-darwin10.7.0] )

$ ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.7.0]

Rails development is Ruby on Rails in development mode.

Environment: MacBook Pro, 2.26GHz, 4G ram, OS X 10.6.7 (all updates applied), XCode 3.2.6

STEPS TO REPRODUCE:
$ gem install rake
$ gem install rails
$ rails new crash_test
$ cd crash_test
$ gem install bundler
$ rm public/index.html
$ nano Gemfile

Gemfile

source 'http://rubygems.org'

gem 'rails', '3.0.7'

gem 'sqlite3'
gem 'compass'
gem 'haml'
gem 'devise'
gem 'cancan'
gem 'prawn'
gem 'prawn_rails'

group :development, :test do
gem 'awesome_print'
gem 'itslog'
end

save Gemfile

install all gems and dependencies

$ bundle install

create a model, view, and controller

$ rails g scaffold user name:string occupation:string

create database and schema

$ rake db:migrate

insert some data

$ rails c

User.create(:name => "mickey mouse", :occupation => "programmer")
User.create(:name => "donald duck", :occupation => "gamer")
User.create(:name => "goofy", :occupation => "president")
exit

start rails server (webkit)

$ rails s

IN ANOTHER TERMINAL WINDOW

$ ab -n 1000 -c 2 http://localhost:3000/users

When I run apache bench (above), ruby will crash with the following (sometimes, read below):

ruby(89829,0x104a81000) malloc: *** error for object 0x100000000: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap

Some times, ruby will crash with the following:

10:28:42 active_record User Load (0.7ms) SELECT "users".* FROM "users"
10:28:42 action_view Rendered users/index.html.erb within layouts/application (17.0ms)
10:28:42 action_controller Completed 200 OK in 44ms (Views: 29.5ms | ActiveRecord: 0.7ms)

-- C level backtrace information -------------------------------------------

[NOTE]
You may have encountered a bug in the Ruby interpreter or extension libraries.
Bug reports are welcome.
For details: http://www.ruby-lang.org/bugreport.html

Abort trap

IMPORTANT: ruby will not crash every time I run apache bench! But I can eventually get it to crash. You may need to exit (crtl-c) rails server and restart it (rails s), then run apache bench again. Sometimes, it takes 4-10 times of restarting rails server and then hitting it with apache bench for it to crash. But I can reproduce the crash.

I believe there is some interaction with the 'awesome print' gem or the 'itslog' gem that is causing the ruby crash, because if I eliminate one or both of those gems, ruby does not crash (in my limited testing). Which ever the case, RUBY is crashing with an exception type of EXC_CRASH (SIGABRT).
