From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You're talking about 2 things: 1. Strict aliasing to guarantee nobody does anything stupid with the pointers, and 2. Bounds checking at compile time with runtime checks for anything that cant be guaranteed at compile time.
There are analysis passes that do this, coverity did some, as does gcov though less well.
