In a template function I have this code:

   typedef V::ValueType ValueType;

   std::vector<ValueType> vecTmp(5);
   for (int i=0; i <5; i++) {
     vecTmp[i] = paramCurrent[i];

So, I take it 'paramCurrent' is an array of 'V::ValueType'.

   }

   std::vector<ValueType>::iterator it = vecTmp.begin();
   for (int j=0; j<2; j++) {
     ValueType val = deform[j];

OK, so 'deform' is also an array of 'V::ValueType'.

vecTmp.insert(it, val);
}

But when I try to insert an element where the "it" iterator is pointing

How?

I get the error:

unknown location(0): fatal error in "test_array": G:\Programs\Microsoft
Visual Studio 9.0\VC\include\vector(251) : Assertion failed: vector
iterators incompatible

I don't see 'test_array' anywhere your example.

I am using VS 2008 on vista 64. I cannot see the problem. Both the
vector and the iterator are intialized with the ValueType.

That's nonsense. An iterator can only be initialised with an iterator.
