描述

@mossberg

I find it mildly unsatisfying that if Manticore crashes while in the executor loop, the process will still return 0 (meaning subprocess.check_output or check_call will not catch it). But that's an issue for a later time.

研究方向
Investigate the executor loop in Manticore, likely in the main execution file (e.g., manticore/core/executor.py). Determine where the process exit code is set and ensure that exceptions during the executor loop result in a non zero exit code. Look at the main entry point and how it catches exceptions. There is no linked PR or assignee, so this is open for research. The issue was reported in 2018, so check the current codebase for changes.
