当 python extension(用 C 编写)试图访问无法访问的内存时会发生这种情况.

This happens when a python extension (written in C) tries to access a memory beyond reach.

您可以通过以下方式对其进行跟踪.

You can trace it in following ways.

• 添加 sys.settrace 在代码的第一行.

• 使用 Mark 在 this answergdb/a>.. 在命令提示符下

• Add sys.settrace at the very first line of the code.

• Use gdb as described by Mark in this answer.. At the command prompt

gdb python
(gdb) run /path/to/script.py
## wait for segfault ##
(gdb) backtrace
## stack trace of the c code
