I have a macro inside two namespaces, and the most important thing - before the macro is a comment without indentation. If you delete one namespace, or delete a comment, or add a tab in front of comment, there will be no crash
```hlsl
namespace TextureSet {
        namespace Tools {



// TODO: template <typename T> in HLSL 2021
#define NormalizeTest_TEMPLATE(T) \
        T NormalizeTest(const in T value) \
        { \
                return value - (1.0f / 128.0f) * value * (1.0f - value); \
        }


}}
```
.clang-format
