Not everyone c++ constructions has been parsed well

Hello.
I have doxygen Version: 1.5.5 for Win32

It seems that, i can't get all reversed documentation using doxygen.

See example:

template <class T1,class T2>
class iA
{...};

template <class T>
class iB
{...};

template <class T1,class T2>
class C
  : public iA<T1,T2> //doxy error, but c++ eats
  , public iB<C<T1,T2>> //doxy error, but c++ eats
{...};

My MSVS.NET 2005 SP1 works well with it.
But doxy generate nothing about class C. Only abount .h and .cpp files 
containing it. No class diagramms, no relations.

My doxygen works well when my code looks like, but c++ reports errors:

template <class T1,class T2>
class iA
{...};

template <class T>
class iB
{...};

template <class T1,class T2>
class C
  : public iA //c++ error, but doxy eats
  , public iB //c++ error, but doxy eats
{...};

Question:
Is it doxygen bug, or i'am a dummy?

ps: sorry about my english localisation :)
