[Python-Dev] gcc 4.2 exposes signed integer overflows
I discovered that gcc 4.2 exposes a flaw with signed integer overflows in python. This bug and the necessary fix has been discussed in detail on the gcc mailing list. I have filed a detailed bug report and the recommended patch proposed by the gcc developers. This problem should be addressed BEFORE python 2.5 is released. The bug report is... [ 1545668 ] gcc trunk (4.2) exposes a signed integer overflows in the python sourceforge bug tracker. Thanks in advance for attempting to fix this before Python 2.5 is released.

Re: [Python-Dev] gcc 4.2 exposes signed integer overflows
Guido, You'll never win that argument with the gcc developers. If you rely on undefined behavior in the c language standard, they have in the past, and will continue to, feel free to ignore those cases. If you plan on ignoring this issue, just be prepared to see a testcase failure in the python testsuite when python is built with gcc 4.2.

Re: [Python-Dev] gcc 4.2 exposes signed integer overflows
I believe some of the others here might be interested in some other postings on the gcc mailing list regarding this issue (which weren't cross-posted here)... http://gcc.gnu.org/ml/gcc/2006-08/msg00516.html http://gcc.gnu.org/ml/gcc/2006-08/msg00517.html It makes clear that the impact of this change in gcc was considered and the reasoning on their decision to follow the standard so closely. http://gcc.gnu.org/ml/gcc/2005-06/msg01238.html Just so other beside Guido see those.

[Python-Dev] python, lipo and the future?
I am curious if there are any plans to support the functionality provided by lipo on MacOS X to create a python release that could operate at either 32-bit or 64-bit on Darwin ppc and Darwin intel? My understanding was that the linux developers are very interested in lipo as well as an approach to avoid the difficulty of maintaining separate lib directories for 32 and 64-bit libraries. Thanks in advance for any insights on this issue.

Re: [Python-Dev] python, lipo and the future?
Martin, I believe if you use the Xcode project management the Universal binary creation is automated. Currently they support the i386/ppc binaries but once Leopard comes out you will see i386/x86_64/ppc/ppc64 binaries for shared libraries.

[Python-Dev] 2.5.2 schedule?
I was wondering if there is a schedule for the release of a python 2.5.2 update? I don't see anything like that on the www.python.org web site. Thanks in advance for any information.
