2 consecutive commands into interactive shell still results in segmentation fault 11, patch 18458 reports skipped as patch not needed for 3.3

Works for me using the python.org 3.3.3 64-/32-bit installer.  Are you using that Python 3.3.3?  Please show the results of typing the following commamds and substituting for "python3.3" whatever command name you are using that causes the segfault.

python3.3 -c 'import sys;print(sys.version)'
python3.3 -c 'import readline;print(readline.__file__)'
ls -l $(python3.3 -c 'import readline;print(readline.__file__)')
python3.3
1
2
3
quit()

You should see:

I don't get to enter the final 3, the segmentation fault happens after 
the second input line.

Your Python installation picks up the wrong readline module.

Christian is correct. /System/Library/Frameworks is the location of the Apple supplied system Pythons and further Apple does not ship any version of Python 3. So you should figure out how your /System/Library got altered and restore it to release state.

Many thanks for your prompt assistance
