Fwd: fastcgi & continuations (Re: Idea: Webshare)

Hello,

T suggested that ruby-core would be an appropriate place for this.  I 
think I've found a Mac OS X bug.  Here is the example:

    continuation = []
    at_exit{
      puts 'at_exit'
      continuation[0].call unless continuation[0].nil?
    }
    callcc{ |c|
      continuation[0] = c
    }
    puts 'running'

This code runs in the expected continuous loop on linux.  On my mac
(10.2) I get the error:

    [~/programming/narf] patsplat% ruby bug.rb
    running
    at_exit
    running
    bug.rb:9: compile error (SyntaxError)
    bug.rb:9: [BUG] Bus Error
    ruby 1.8.1 (2003-12-25) [powerpc-darwin]

    Abort
    [~/programming/narf] patsplat%

Does this happen on any other platform?  Is this an OS X limitation?

Cheers,

Patrick
