Chrome OS has a fairly extensive FORTIFY test suite for both
compile-time and run-time diagnostics. It covers tons of edge cases, and
conveniently centralizes diagnostic and death testing.
A fair amount of it has been ifdef'ed out, since Bionic doesn't yet
diagnose (or crash on) some of these things. The intent is to explicitly
declare defeat on the things we don't care to FORTIFY, and slowly fix
the rest in easier-to-digest CLs.
Once that's done, we might be able to look into retiring some of the
FORTIFY testing that we don't share with the CrOS folks.
