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. Jack

Regardless of whether we consider gcc's behaviour to be correct or not, I do agree we need a fix for this in 2.5 final. That should also be backported to release24-maint for the 2.4.4 release, and maybe release23-maint, as Barry recently started talking about cutting a 2.3.6.

Can I nominate Tim, with his terrifying knowledge of C compiler esoterica, as the person to pick the best fix?

Thanks, Anthony
