Re: [v8-users] Debugging mksnapshot bus error

That did resolve the issue, but I'm not 100% positive it's a heap size issue. I was able to whittle my snapshot file down to a much smaller subset (55.1 MB down to 83 KB for the input file) and it still causes the same problem. The updated file is in this gist
