--- Comment #1 from Dlang Bot <dlang-bot@dlang.rocks> ---
@MoonlightSentinel created dlang/dmd pull request #13751 "Fix 22031 - Allow modification of non-mutable in `crt_[con|de]structor`'s" fixing this issue:

- Fix 22031 - Allow modification of non-mutable in `crt_[con|de]structor`'s

  Allow functions marked as `pragma(crt_[con|de]structor)` to modify
  `const` / `immutable` variables, which is currently restricted to
  module ctors / dtors. This enables the use of lazily initialized global
  constants for applications without druntime.

  Such function may not be called at runtime because they might violate
  the guarantees of `const` / `immutable`. Hence it is now an error to
  call a function marked as `pragma(crt_[con|de]structor)`.
