angr.exploration_techniques.Tracer() got an unexpected keyword argument 'copy_states'

When I run shellphuzz I get the following:

WARNING | 2018-11-28 13:11:27,135 | local_callback | starting drilling of buggy, id:000000,orig:seed-0 Traceback (most recent call last): File "/home/kburova/.virtualenvs/devis/lib/python3.5/site-packages/driller/local_callback.py", line 122, in <module> for new_input in d.drill_generator(): File "/home/kburova/.virtualenvs/devis/lib/python3.5/site-packages/driller/driller_main.py", line 101, in drill_generator for i in self._drill_input(): File "/home/kburova/.virtualenvs/devis/lib/python3.5/site-packages/driller/driller_main.py", line 128, in _drill_input t = angr.exploration_techniques.Tracer(trace=r.trace, crash_addr=r.crash_addr, copy_states=True) TypeError: __init__() got an unexpected keyword argument 'copy_states' (b'', None)

I assume the version of tracer.py is wrong under angr/exploration_techniques/. I installed angr using command pip install angr. When I use python setup.py install within angr repo folder, I get correct tracer.py, but then lib/angr_native.so is missing. Any suggestions on how to fix all this, and what needs to be installed/reinstalled? Thanks

Wow, that was easier than I thought. I integrated the above patch slightly differently in https://github.com/angr/angr/commit/31d5bb0c1d787427cdb95fc600619f064309eaa4. This should be resolved now.

I also encountered the same exception All states disappeared!. I checked various variables around this code, e.g., step_step() and _update_state_tracking(), and found that state.history.jumpkind indicates Ijk_Exit. It is not seem to be a critical error/exception. So, I added the following if branch to drop the exception.

https://github.com/angr/angr/blob/master/angr/exploration_techniques/tracer.py#L210-L212

elif self._compare_addr(self._trace[idx + 1], state.addr):
    if state.history.jumpkind.startswith('Ijk_Exit'):
        # termination!
        state.globals['trace_idx'] = len(self._trace) - 1
    else:
        # normal case
        state.globals['trace_idx'] = idx + 1

BTW, this is an issue of angr not driller…
