RegExp Regular Expression execution incorrect

Project Member Reported by tflo@google.com, Apr 19 2016 
UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 Safari/537.36

Steps to reproduce the problem:
1. Open this JsFiddle repro: https://jsfiddle.net/32kv6oce/
2. Click Run a bunch

What is the expected behavior?
Prints "class" consistently

What went wrong?
Sometimes it prints "class".  Oftentimes it prints:

"class Foo {
  /**
   * @param {string} foo
   */
  co"

Did this work before? Yes Chrome 49

Chrome version: 50.0.2661.75  Channel: stable

Yup, confirmed the issue, and it looks buggy to me.

I expect this is actually a v8 issue. Hopefully someone will re-triage it over there. I'm not sure if this is a Javascript or Javascript>Runtime ...

yangguo@chromium.org,

Out of curiosity, why was this dup'd to 604897?  This is the older bug.

Comment 6 by yangguo@chromium.org, Apr 20 2016 

No particular reason. There is no rule that prescribes any deduplication order. I already included the necessary information in the other bug, so that seems the suitable choice.

Comment 7 by tflo@google.com, Apr 20 2016 

Cool.  No worries.
