From 40b2a4a793c81221a28f822d07135069456ea021 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Tests: fix: parse-callback reports missing addr2line
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Upstream-Status: Backport

addr2line from binutils is required for this script to work correctly.
However, it silently fails. Fix this by using `subprocess.run' with
`check=True' instead of `subprocess.getoutput'. That way, an exception
is raised if an error occurs.

Fix the shebang by not assuming where python is installed while at it.
