← Logic & PuzzlesWhat happens to a compiler's verification process when the negation of a key optimization invariant leads to detectable program failure?
A)Optimization silently skips the error
B)Compiler flags optimization as unsafe✓
C)Optimization proceeds without warning
D)Error is masked by other optimizations
💡 Explanation
The compiler flags the optimization as unsafe because proof by contradiction identifies a flaw in the optimization. The program detects failure because a supposed invariant doesn't hold. Therefore, the compiler recognizes the error, rather than proceeding or silently skipping.
