[Bug c++/38063] New: C++ operator new returns misaligned address

[David dot Monniaux at imag dot fr]

On IA32, operator new returns an address multiple of 8 in all cases, even if
called on a type with strict alignment (16).

typedef double double2 __attribute__ ((vector_size(16)));

int main() {
  std::cout << __alignof__(double2) << " " << ((void*) new double2) <<
std::endl;
}

returns:
16 0x8107008
