--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.  Missed gimplification:

#1  0x0000000001c12d7e in verify_gimple_stmt (
    stmt=<gimple_with_cleanup_expr 0x7ffff71cea80>)
    at /space/rguenther/src/gcc/gcc/tree-cfg.cc:5169

try
  {
    <<< Unknown GIMPLE statement: gimple_with_cleanup_expr >>>

    D.2795 = {};
    D.2796 = &D.2795;
    MEM[(int *)D.2796] = {CLOBBER(eob)};
  }
finally
  {
    operator delete (D.2796, 4);
  }


clang complains:

t.ii:3:7: error: cannot delete expression of type 'T' (aka 'int[2]')
    3 |       delete T{};
      |       ^      ~~~
