typedef float float4[4]; std::vector<float4>; does not compile, why?

The following code will not compile in gcc 4.3.2 on Ubuntu 8.10

#include <vector>

typedef float float4[4];

int main()
{
  std::vector<float4> vals;
}

I get the following compilation error:
/usr/include/c++/4.3/bits/stl_construct.h: In function =91void
std::_Destroy(_Tp*) [with _Tp = float [4]]':
/usr/include/c++/4.3/bits/stl_construct.h:103: instantiated from

/usr/include/c++/4.3/bits/stl_construct.h:88: error: request for
member =91~float
[4]' in =91* __pointer', which is of non-class type =91float [4]'

The code does compile in gcc 3.4 and gcc 4.1. So I'm guessing this is
because of some "enlightened" understanding of the C++ standard?
Please enlighten me.
