[issue19366] Segfault in REPL due to escaped tab.

2013-10-23 Thread George King 

New submission from George King:

I can crash python2.7.5 python3.3.2 from the REPL consistently:

$ python3
Python 3.3.2 (v3.3.2:d047928ae3f6, May 13 2013, 13:52:24) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type help, copyright, credits or license for more information.
 s = '\\t'
 s
Segmentation fault: 11
$ 

the same goes for:
Python 2.7.5 (v2.7.5:ab05e7dd2788, May 13 2013, 13:18:45) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin

both of these python builds are the mac binaries from python.org.

George King added the comment:

actually, the second line of any interactive session is segfaulting; my 
installation must be corrupted.

George King added the comment:

this is probably due to system upgrade from OS X 10.8 to 10.9 (mavericks) 
yesterday.

2013-10-23 Thread Ned Deily 

Ned Deily added the comment:

This is a duplicate of Issue18458. The problem is due to an incompatible update 
to the GNU readline compatibility layer of the editline shared library 
(libedit) in OS X 10.9.  The fix for this will be in the upcoming Python 2.7.6 
and 3.3.3 maintenance releases, expected soon. In the meantime, the workaround 
proposed in the Stackoverflow comment will eliminate the crash.  (Issue18458 
will be updated shortly to include a script to do this.)

2013-10-23 Thread George King 

George King added the comment:

thank you. i worked around this by building python3 from source, with gnu 
readline libs i had previously compiled (those did not require a rebuild on osx 
10.9).
