--- Comment #6 from Martin Li=C5=A1ka <marxin at gcc dot gnu.org> ---
Started with r12-6375-g6cd51207f5732b52.

Reduced test-case:

$ cat pr104084.C
int nothrow;
struct MaxAlignedAllocable {
  void *operator new[](unsigned long, int);
  void operator delete[](void *);
  long Resize_size;
  void Resize() { new (nothrow) MaxAlignedAllocable[Resize_size]; }
};=
