Any idea what might be causing this?

[GBH]

Seems there was an issue with my setup. OSX Lion + XCode 4.2.beta
Uninstalling XCode and installing 4.1 and then rebuilding ruby in rvm fixed the issue.

[dimaspriyanto]

did you use XCode version 4.2 (4D199), i experiencing the same segfault issue?

[GBH]

I had 4.2 beta installed. Something that was available when Lion came out. Worked just fine until I got segfaults for this project.

[dimaspriyanto]

the error was caused by compiler that you use when installing ruby, apple now use LLVM than GCC, i wrote a log how i fix it here: http://dimaspriyanto.com/2011/10/30/getting-ruby-1-9-fiber-to-work-with-xcode-4-2-on-osx-lion-10-7/

[GBH]

Thanks for the investigation efforts. At least now I know what was causing this.
