>How-To-Repeat:
//this is the source
//use g++ -g -c WordIndex.C

namespace LongVirtualMemory {

  template <class size_t>
  class LinearMem
  {
    struct BlockHead
    {
      size_t size;
    };
    typedef int ii;
    ii ReadBlockHead();
    virtual readDev(){};
  public:
    LinearMem_(){readDev();}
  };

  mmm()
  {
    LinearMem<int> ll;
    ll.LinearMem_();
  }
}
>Fix:
take out 'namespace' or 'virtual' or 'struct.'
Any one will force error free compilation.
