# performance-noexcept-destructor

The check flags user-defined destructors marked with `noexcept(expr)` where `expr` evaluates to `false` (but is not a `false` literal itself).

When a destructor is marked as `noexcept`, it assures the compiler that no exceptions will be thrown during the destruction of an object, which allows the compiler to perform certain optimizations such as omitting exception handling code.
