--- Comment #3 from Dlang Bot <dlang-bot at dlang.rocks> ---
dlang/dmd pull request #14701 "merge stable" was merged into master:

- d836c8bcec16205644e3aacf15f1a1cf7d655dd5 by mhh:
  Fix Issue 23549, 22587 - Lower certain noreturn expressions to a comma
expression rather than a cast.

  This avoids a backend segfault.

  GDC already does this lowering so it may have to be made optional via a
frontend parameter.
