Driller not generating valid inputs about driller

[salls]

I think the fix is to not remove the constraints that match preconstraints. In line 591 of tracer/tracer.py change new_constraints = filter(lambda x: x.cache_key not in precon_cache_keys, path.state.se.constraints) to new_constraints = path.state.se.constraints.

I believe this was necessary in the old style of preconstraining before we switched to the replacement frontend. If so, and the filter isn't necessary, making this change should not break any existing tests and will fix this issue.

angr/tracer#18 should fix it. Waiting for some tests before I merge it

Merged, this issue should be fixed

Looks to be fixed on my end too! Thank you!
