Segmentation fault (core dumped) on OpenBSD 5.1 (amd64) #8

Open ghost opened 12 years ago

ghost commented 12 years ago

I try invoking a web.py app, but got a core dump immediately:

# pytrace myscript.py 
http://0.0.0.0:8080/    # <-- Here is OK, after access port 8080 with a web browser, it terminates.
Segmentation fault (core dumped)

Anything i can do to see why it terminates?

alonho commented 12 years ago

several options here:

  1. show me the stack trace by running: gdb python -c CORE_FILE_NAME
  2. send me the core (alonho@gmail.com) - know that the core file might contain sensitive information, don't send it if your python modules contains secret keys or such.
  3. wait a few days until I have the time to try and reproduce it myself.

Thanks!

could you invoke the 'bt' command so i'll get a full stack trace. all I can see here is that it crashed within memcopy. what version of openbsd are you using? i'll install one myself.

Hi Alon,

I uploaded the core file here: http://173.254.22.21/python2.7.core.bz2 (about 5.5MB), you can debug it directly. It's generated on a testing machine, so there's no sensitive info at all.

I'm running OpenBSD 5.1 (amd64) in a VMware machine. Thanks for your help.
