Description Diego Elio Pettenò (RETIRED) gentoo-dev

You're receiving this bug because the package in Summary has produced _FORTIFY_SOURCE related warnings indicating the presence of a sure overflow in a static buffer.

Even though this is not always an indication of a security problem it might even be. So please check this out ASAP.

By the way, _FORTIFY_SOURCE is disabled when you disable optimisation, so don't try finding out the cause using -O0.

Thanks,
Your friendly neighborhood tinderboxer

Please add emerge --info as I cannot reproduce it on my system with gcc-4.4.4-r2 and glibc-2.12.1-r1
