I tested faulthandler on Linux, FreeBSD and Windows XP: it works well. I suppose that it works on any operating systems.

You can also try it on know crashers: Lib/test/crashers/ (you have to modify the files to add: import faulthandler; faulthandler.enable()). Example:

----
$ ./python Lib/test/crashers/bogus_code_obj.py 
Fatal Python error: Segmentation fault

Traceback (most recent call first):
  File "", line 1 in 
  File "Lib/test/crashers/bogus_code_obj.py", line 20 in <module>
Erreur de segmentation
----

The backtrace is not revelant here because the file is very short, but faulthandler is more useful on an huge application.
