Steps to reproduce the problem:
Hi , 

Buy running the attached file (sock.html) make the browser crash at /csu/libc-start.c:291 
However, I can reproduce this in Windows, Linux OS with various version like Chrome, Chrome Beta, Chromium.

By running the sock.html file in Windows OS; in Chrome takes the System usage to 100%

Please find the GDB log/trace for Chromium in Linux and for repro please open (sock.html) file in any platform and versions of chrome.

What is the expected behavior?

What went wrong?
