Description

This test case tests the functionality of the ABRT together with EasierPythonDebugging.


How to test

  1. Run the following python script that abuse the ctypes module in such a way as to cause /usr/bin/python to segfault/abort.
    1. First, cause a segfault 
      

      python -c "import ctypes; ctypes.string_at(0xffffffff)"
      

      Segmentation fault (core dumped)
      2. 

    2. Next, cause a core dump

      

      python -c "import ctypes; ctypes.string_at(0x0)"
      

      python: Objects/stringobject.c:115: PyString_FromString: Assertion `str != ((void *)0)' failed.
      

      Aborted (core dumped)
    2. 

  2. Next, repeat all of the above for python3
    3. 

  3. Finally, repeat the steps for python3-debuginfo


Expected Results


  1. In each case, there should be meaningful information at the Python level, as well as at the C level in the bactrace.
