From initial investigation it looks like the "-Werror=format-security" CFLAGS/CXXFLAGS in ext/http11/Makefile is exposing this error. Removing the same gets through the build. But that is not the right fix. The flag is default set in Ubuntu and RHEL build environments. Hence right fix would be to ensure actual code where the flag is reporting an error is rectified appropriately.
