Georg Brandl added the comment: Looks obvious and is potentially a security fix, so it can/should go in.

[issue19529] Fix unicode_aswidechar() with 4byte unicode and 2byte wchar_t, for AIX
Michael Haubenwallner added the comment: It is the abort() libc function being called, causing a core file to be written. And I can see the backtrace from both the core file or when running in the debugger. Yes: I already have included this fix into my python-3.2.5 packaging. I'm basically fine when this patch is accepted technically, although I'd prefer to see it included in the next 3.2 release, if any. In fact I've reported it only because I've seen a 2.7 release recently - ohw, and 2.6.9 yesterday, so I've expected there eventually may be another 3.2 release too. Yes: This bug does not exist since 3.3 any more due to the rewrite. And indeed I'd also call this a security fix because it is of the invalid memory read type: I do see the filenames being truncated after 112 characters when building in some longer build-path.

[issue19529] Fix unicode_aswidechar() with 4byte unicode and 2byte wchar_t, for AIX
New submission from Michael Haubenwallner: The problem raises during build already when trying to run setup.py, where ./python is unavailable to locate the 'encodings' module and aborts. It turns out that (some of) the filenames searched for are broken due to wrong conversion from unicode (across wchar_t) to char. Attached patch is for 3.2 only, should be obvious enough.

Terry J. Reedy added the comment:
By 'crash' ('abort'), do you mean segfault (or Windows equivalent) or an exit
with traceback? 3.2 only gets security patches. Do you think this is a security
issue? Does the problem exist with the latest 3.3 or 3.4?

[issue19529] Fix unicode_aswidechar() with 4byte unicode and 2byte wchar_t, for AIX
STINNER Victor added the comment: The bug is obvious and patch looks good to me. The problem is that Python 3.2 doesn't accept bugfixes anymore, any security fixes. http://www.python.org/dev/peps/pep-0392/ 3.2.5 schedule (regression fix release) 3.2.5 final: May 13, 2013 -- Only security releases after 3.2.5 -- Georg Brandl, the release manager, may reconfirm that. How is Python packaged on AIX? Can you integrate your fix in your package for Python 3.2? The unicode type has been completly rewritten in Python 3.3, the bug was indirectly fixed during the rewrite. @Michael: can you confirm? You have to compile Python = 3.3 in debug mode and run the test suite (./python -m test -j0 -r). -- nosy: +haypo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19529 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
