Description
Fome some versions of gcc/glibc a warning will be produced with FORTIFY_SOURCE is used without optimizations enabled (see here for related information https://sourceware.org/bugzilla/show_bug.cgi?id=13979). This only happens in some environments such as CentOS 7 and Arch Linux with GCC 6.2.
Probably one of the reasons why it didn't get caught earlier by CI:
"This #warning appears to be causing more grief than it is solving; for example, see this autoconf thread that complains that it is breaking configure scripts, and therefore Debian's decision to revert this patch in their build of glibc:
