--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---

Remove the null check from placement new in all modes
gcc/cp/
Remove the null check from placement new in all modes
* init.c (build_new_1): Don't do a null check for
a namespace-scope non-replaceable placement new
in any mode unless -fcheck-new is provided.
