- Introducing the Constexpr Debugger in CLion 2025.3 EAP for debugging compile-time C++ code.
- Allows stepping through constexpr evaluations, inspecting values, and identifying failed branches.
- Supports features like Step Into, Step Over, Step Backward, and variable inspection.
- Useful for debugging compile-time Fibonacci cache and other constexpr functions.
- Highlights edge cases like non-constexpr calls preventing evaluation.
- Current limitations include no breakpoints, limited C++20 modules support, and some unsupported constructs.
- Encourages user feedback for further improvements.
