Python 子进程返回 -11

Question

我正在做一个测试用例，每当我调用子流程时，我都会收到以下错误。

  File "/usr/lib/python2.7/subprocess.py", line 540, in check_call
    raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['/usr/bin/python', 'TestRunner/TestRunner.py', '-r', '1000000']' returned non-zero exit status -11

问题是，我应该如何提取实际的错误消息？

我没有从退出状态 -11 中得到任何信息。

是否有存储错误详细信息的临时文件？

谢谢。

Answer 1

手动尝试运行命令：

/usr/bin/python TestRunner/TestRunner.py -r 1000000

如果 -11 return 被解释为 "exited with signal 11 (Seg fault)"，shell 应该打印一条这样的消息。

Answer 2

详细说明我的评论：

基于link I provided, it looks like you're running into a segfault because a thread did something it wasn't supposed to. Perhaps it would be helpful to check out this link as well: https://wiki.python.org/moin/CrashingPython
