Hi.  I'm running io installed via the homebrew package manager on OS/X (whi=
ch pulls down the 2011.09.12 tag of io).  It's currently installed with yaj=
l 2.0.4 on my Mac running OS/X Mountain Lion (10.8.2).

I'm trying to run the test script from addons/Yajl/test.io and it throws a =
segfault whenever I run it.  I'm running verbatim from here:

     https://github.com/stevedekorte/io/blob/master/addons/Yajl/test.io

I spent a bit of time breaking up the last few expressions and determined t=
hat it's actually the asJson call which is causing the error.  However, for=
 some cases the sequence is working OK.

    $ io
    Io 20110905
    Io> Yajl clone parse("""{}""") root asJson
    =3D=3D> [{}]
    Io> Yajl clone parse("""{"abc": [1, 2, 3]}""") root asJson
    zsh: segmentation fault  io

This is the formula that homebrew uses to install Io, if that's helpful.  I=
t does install a patch or two, but nothing that seems terribly relevant to =
this case.

    https://github.com/mxcl/homebrew/blob/master/Library/Formula/io.rb

Can anyone reproduce this behavior on any other architectures, or more gene=
rally point me in the right direction in fixing this bug?

Thanks
Tim
