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.

Attached is a patch, which fixes the warning, by specifying the correct constant.
The changes in the bug probably require a revbump.
Shall I file a new ticket with a revbump, which would incorporate the changes, as well as changes proposed in #526530?
