When an operation would overflow during constant evaluation, the compiler emits error E0453. This error typically surfaces during const function calls, generic constant expressions, or array length computations where the result exceeds the representable range of the target integer type.</p> <h2 id="1-symptoms">1. Symptoms</h2> <p>Error E0453 manifests during the compilation phase, specifically during the monomorphization or const evaluation passes. The compiler halts with a diagnostic message that pinpoints both the location of the overflow and the specific operation that caused it.</p>
