python-lang causing Alignment trap and Segfault

python-lang causing Alignment trap and Segfault

[Josh Kropf]

I've compiled an image for my mini2440 board (armv4t) from the 
stable/2009 branch in git using angstrom distribution.

One of the python packages I need depends on python-lang but I'm finding 
that python segfaults when python-lang is installed.  The kernel logs 
the following before the segfault:

Alignment trap: python (2303) PC=0x403f007c Instr=0x28001c05 
Address=0xffffffff FSR 0x813

Removing python-lang package makes python work again.

Just wondering if anyone has run into this problem or has some pointers 
on debugging this.

Thanks,
- Josh

Try running python -v to find out exactly which module is triggering  
that.

Cheers,

Looks like the atexit module

root@mini2440:~# python -v
[snip]
# /usr/lib/python2.6/atexit.pyo matches /usr/lib/python2.6/atexit.py
import atexit # precompiled from /usr/lib/python2.6/atexit.pAlignment 
trap: python (2329) PC=0x403f007c Instr=0x28001c05 Address=0xffffffff 
FSR 0x813
yo

Just wanted to update the list on this issue.

I have no idea why, but after removing the readline.so file (from 
/usr/lib/python2.6/lib-dynload/) python no longer segfaults on startup.
