Here is a better backtrace:

And a reduced testcase:
typedef __SIZE_TYPE__ size_t;
inline void* operator new[](unsigned, void* __p) throw() {  return __p;  }
void *malloc(size_t);
template<typename DataT>   inline   void ConstructRawArray(DataT *data,unsigned
size) {
     new(data) DataT[size];
}
template<typename DataT>   struct SingleBufferBodyC  
{
  DataT *buff;
  void *operator new(size_t s,void *mem)        {       }
  inline unsigned Size() const          {        }
  SingleBufferBodyC(unsigned nsize)    
  {    
  ConstructRawArray(this->buff,this->Size());  
  }
};
template<typename DataT>   struct SingleBufferC   
{
  SingleBufferC(unsigned size)     
  {
     SingleBufferBodyC<DataT> *ret = reinterpret_cast<SingleBufferBodyC<DataT>
*> (malloc(8)) ;   
     new(ret) SingleBufferBodyC<DataT>(size);    
  }
};
struct TestObjC {
 TestObjC()   { }
 int val;
 };
int TestSingleBuffer() {
   SingleBufferC<TestObjC> buff3(100);
}
