@n8sh created dlang/druntime pull request #3264 "TypeInfo.swap must not allow
reachable memory to be freed if interrupted by a garbage collection pass"
fixing this issue:

- Fix Issue 21365 - TypeInfo.swap must not allow reachable memory to be freed
if interrupted by a garbage collection pass

  If the type might contain pointers perform the swap in pointer-sized
  chunks in case a garbage collection pass occurs partway through the
  function. Directly affected TypeInfo subclasses that were not
  overriding swap:

  - TypeInfo_AssociativeArray
  - TypeInfo_Class
  - TypeInfo_Delegate
  - TypeInfo_Interface
  - TypeInfo_Struct
