Expected behavior

proj = angr.Project('/bin/true') should hopefully be able to complete.

Actual behavior

Some thread exception seems to happen when run from the r2 shell line. However, if I #!python and do it from there it works fine.

Steps to reproduce the behavior

Example base:

import r2lang
import sys
import angr, claripy
from time import sleep

class R2Symbion(object):
    def _call(self, s):
        s = s.lower()

        # Not for us
        if not s.startswith('symb'):
            return

        print('doing it')
        p = angr.Project(r2.cmdj('ij')['core']['file'])

    def plugin(self, a):
        return {
            "name": "R2Symbion",
            "licence": "GPLv3",
            "desc": "Integration plugin for angr Symbion.",
            "call": self._call,
        }

r2symb = R2Symbion()
success = r2lang.plugin("core", r2symb.plugin)

This gives an exception:

• r2 -i ./base.py /bin/ls
• symb # doesn't actually do anything
• exit # Shows the thread error

Exception ignored in: <module 'threading' from '/usr/lib/python3.6/threading.py'>
Traceback (most recent call last):
  File "/usr/lib/python3.6/threading.py", line 1289, in _shutdown
    assert tlock.locked()
SystemError: <built-in method locked of _thread.lock object at 0x7fa0a989bd78> returned a result with an error set

However, this works

• r2 -i ./base.py /bin/ls

• !python3

• r2symb._call('symb')
