@MoonlightSentinel updated dlang/dmd pull request #12265 "Issue 21693 - Lower
scoped destruction of extern(C++) class to destroy" mentioning this issue:

- Issue 21693 - Lower scoped destruction of extern(C++) class to destroy

  Ensures proper RAII behaviour for stack allocated instances but doesn't
  affect the behaviour for heap allocated instances.

  The previous rewrite used `delete` which relies on `TypeInfo` and
  crashed at runtime. Using `object.destroy` circumvents this issue (and
  is also beneficial due to the deprecation of `delete`).

  `destroy` can be used instead of `delete` because the instances live on
  the heap and hence don't need to be deallocated.
