--- 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 = b'0xa6308\n'
elf = 'myfile.elf'

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

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