Thank you both, and the issue tracker has proved informative to. I see that at the bottom of the issue linked above, someone is making a change to the code rather than environment, and am hoping this will fix the issue also. Not that I'm against the fix as provided, but we use a buildbot tester that pulls in the latest version of things, and having to provide custom build options and patches isn't ideal.
Once the latest build of V8 is working without this issue, I'll bug the Node devs to use the latest version so this issue is fixed. Thank you both.
