<pre>Hehe, my broken code broke clang!
To repro (will take time and requires a powerful machine):
- Check out Chrome at 560d48f40a669bfaf06a830d0cefb926628b0ed1 (commit pos
refs/heads/master@{#308331})
- Apply patch set #2 of <a href="https://codereview.chromium.org/799983002/">https://codereview.chromium.org/799983002/</a> with git
apply
- Build Chrome
This compiler crash repros 100% for me.
