The problem is that this system has a default libc that has been compiled without frame pointers, so any stack walking stops at the libc layer, producing a partial stack that's missing the application frames. Apart from library code, maybe your application doesn't have frame pointers either, in which case everything is broken.

Created by Alastair Robertson , bpftrace is an open source high-level tracing front-end that lets you analyze systems in custom ways. eBPF (extended Berkeley Packet Filter) is in the Linux kernel and is the new hotness in systems engineering. bcc is powerful but laborious to program. It's shaping up to be a DTrace version 2.0:

Selenium was first conceptualized in 2004 at ThoughtWorks for website automation and has come a long way from it’s first Web Driver version to becoming a W3C standard protocol. Small changes in the website source code. Selenium works with certain programming languages. Substantial time is taken to automate. TestComplete.
