UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.87 Safari/537.36

Steps to reproduce the problem:
Not sure about exact steps, I use chromium on 2 different profiles simultaneously and tabs from both profiles keep receiving a SIG11 that crashes either them or the whole browser.
From the segfault traces it looks like a glibc error.

What is the expected behavior?
No random crashes!

What went wrong?
