@MoonlightSentinel created dlang/dmd pull request #13203 "Issue 22300 - Allow
shared <-> unshared reinterpreting casts during CTFE" mentioning this issue:

- Issue 22300 - Allow shared <-> unshared reinterpreting casts during CTFE

  CTFE evaluation is single threaded only, hence it's safe to discard the
  `shared` qualifier in a reinterpreting cast.

  This change allows `-checkaction=context` to use a reinterpreting cast
  for compile and runtime - which removes the problematic workaround
  that caused the regression.
