Subject: [ruby-core:38408] [Ruby 1.9 - Bug #5003] Enumerator#next segfaults in OS X Lion (10.7)


Issue #5003 has been updated by Matthew Conway.


I tired applying the diff from r32201 to 1.9.2p290, and while it mostly works, and seems to fix this problem, it also causes another.  In our rails app, which used to work just fine on 1.9.2p290 on OS X Snow Leopard, I get the following error running a rails console:


/Users/mconway/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.0/lib/rails/commands.rb:21:in `<top (required)>': uninitialized fiber (FiberError)
	from script/rails:10:in `require'
	from script/rails:10:in `<main>'

I built on OS X Lion, using rvm 1.6.25, and XCode 4.1 (4B110) (/usr/bin/gcc)
Not sure if the patch is just not compatible with 1.9.2 branch, or if something else is going on.  A vanilla rails app loads just fine, so could be something in our stack - just weird that it used to work before this patch.
