I've recently played with the GCC implementation of pointer checker on a real hardware, my recent impressions are here: https://github.com/google/sanitizers/wiki/AddressSanitizerIntelMemoryProtectionExtensions (there is also some old pre-hardware content). In short, I totally agree with what David says above: MPX is a disaster. (Usual disclaimer: my opinion here is too biased) I am glad
