Throwing random check doesn't seem like a good idea. For some reason v8 does this: https://github.com/iojs/io.js/blob/v1.x/deps/v8/benchmarks/regexp.js#L40 Wrapping code in IIFE doesn't work because benchmark relies on globals, so the solution is to run code in a new context. |

OK. Thank you for your suggestion. I will try to separate the RegExp benchmark test. |

deps/v8/benchmarks/regexp.js clobbers the RegExp global, breaking util.format() and console.log(). Unclobber it to keep the other benchmarks working. Fixes the following error when running benchmark/misc/v8-bench.js: $ out/Release/iojs benchmark/misc/v8-bench.js util.js:84 if (new RegExp('\\b' + set + '\\b', 'i').test(debugEnviron)){^ TypeError: object is not a function at Object.exports.debuglog (util.js:84:9) at timers.js:12:29 at NativeModule.compile (node.js:800:5) at NativeModule.require (node.js:769:18) at net.js:5:14 at NativeModule.compile (node.js:800:5) at NativeModule.require (node.js:769:18) at tty.js:4:11 at NativeModule.compile (node.js:800:5) at Function.NativeModule.require (node.js:769:18) This could alternatively be addressed by caching the RegExp global in lib/util.js. That's not a bad approach and I considered it but doing it for just RegExp and not other globals would be half-baked. Maybe the more thorough approach where we cache all globals at start-up is something for a follow-up pull request.

I am checking benchmark tests.
When I execute the following tests, I got the errors.
I don't understand why this error is occurred, but I guess
RegExpis not function in vm context.So I just checked RegExp is function, the benchmark test works fine.
