New issue 1423 by [email protected]: "use strict" causes page to crash
http://code.google.com/p/v8/issues/detail?id=1423
1) Open up index.html in attached files in 13.0.779.0 (87105)
2) If it doesn't crash, hit reload a couple of times.
3) Crash stack is below
4) Comment out "use strict"; from remoting.js
5) No longer crashes.
6) Commenting out some of the code in updateAuthStatus_() or moving it to
subroutines appears to get rid of the crash as well.
