In 11.3 release, --enable-default-pie and --enable-default-ssp are enabled for
GCC. They can mitigate some type of malicious attacks but they cannot
provide a full protection. In case if you are reading a programming
textbook, you may need to disable PIE and SSP with GCC options
-fno-pie -no-pie
-fno-stack-protection because some textbooks assume they
were disabled by default.
