[PATCH] D25199: [ubsan] Sanitize deleted pointers

[Matt Gingell via cfe-commits]

Hi Richard,

Thanks for your analysis. 

This patch is intended to mitigate use-after-free bugs. In that context a “define strict behavior for invalid pointer values” we could deploy in production code would be very useful. Maybe calling this a sanitizer is misleading, and instead it could be presented as “change implementation defined behavior to be less convenient but more security friendly."
