Segmentation fault ruby 1.9.2p0 [x86_64-linux]
I'm using The latest ruby 1.9.2 via rvm. on my ubuntu 10.04 64bit AMD machine.
In my rails project. I have a rake tasks that scrapes some web pages using curl based libraries. It randomly fails with the following stack trace
h3. Error message:
/usr/local/rvm/gems/ruby-1.9.2-head/gems/activerecord-2.3.8/lib/active_record/attribute_methods.rb:272: [BUG] Segmentation fault

Can you show reproducible code?
And can you show bucktrace made by a ruby built with -g option.

I think my install of RVM has ruby built with -ggdb so I'm going to attach my own report on the chance that it is helpful.
Until today, I have never encountered this problem. I've been running the same version of ruby for many weeks (I don't recall exactly, but it's been over a month). The only change I can think of is that I updated to Mac OS X 10.6.5 over the weekend. After I encountered the problem this morning, I completely wiped out and reinstalled rvm and all my gems, but the problem persists.
So far the problem seems limited to one action in one controller in my rails app. Even when I pass identical requests to my rails app, roughly two out of three requests will succeed and one will fail. Because of the problem's intermittent nature, I have yet to isolate a good piece of reproducible code.
