Overeager Compilers Can Open Security Holes In Your Code

jfruh writes: "Creators of compilers are in an arms race to improve performance. But according to a presentation at this week's annual USENIX conference, those performance boosts can undermine your code's security. For instance, a compiler might find a subroutine that checks a huge bound of memory beyond what's allocated to the program, decide it's an error, and eliminate it from the compiled machine code — even though it's a necessary defense against buffer overflow attacks."

Unsable Code, again

This is just as poorly written up as last time. These are truly bugs in the programs using undefined parts of the language. It's silly to blame the compiler.
