[MacRuby-devel] Fixing ext/json

[dan sinclair]

Hello,

I've been taking a poke at ext/json for the last few days attempting  
to get JSON support working again. I've got it compiling but have run  
into an issue with memory management and the garbage collector that  
I've been unable to get past.

I've attached my current diff of changes to get JSON working. With  
this diff applied requiring json will crash with:

     unknown: [BUG] destination 0x100feb300 isn't in the auto zone

I've tracked it down to ext/json/lib/json/common.rb line 59 (at least,  
it never gets past that line that I've seen)

     self.state = generator::State

Commenting out this line gets further (require works and I can turn  
{"a" => 1} into JSON. Missing module_function causes JSON.parse to  
fail).

My test file is:

puts "Requiring"
require 'json'
puts "Required"
require 'pp'

puts "to_json"
a = {"a" => 1}.to_json
puts "parse"
pp JSON.parse(a)
puts "done"

Thoughts?

Thanks,
dan
