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.

Still valid with 0.9.1?
Reopening to try to know if this is fixed with latest version

There isn't any QA warning, or "will always overflow destination buffer" warning during compile.
CFLAGS="-march=athlon64 -O2 -pipe -msse3"
So I think this potential security problem is fixed by upstream.
