--- Comment #2 from Luke Diamand <luke at diamand dot org> ---
That works like a charm with my Python test code:


#!/usr/bin/python3

import subprocess
import os

addr =3D b'0xa6308\n'
elf =3D 'myfile.elf'

a2l=3D'eu-addr2line'
p =3D subprocess.Popen([a2l, '-f', '--demangle', '-e', elf],
        stdin=3Dsubprocess.PIPE, stdout=3Dsubprocess.PIPE)

p.stdin.write(addr)
p.stdin.flush()
print(p.stdout.readline())
print(p.stdout.readline())
