Although CINT is not C++, you should try a valid C++ expression.
e.g.
Double_t a[][2]={ {1,2},{3,4} };

or
Double_t b[2][2]={ {1,2},{3,4} };

Thank for your replies. It seems I have to use a[][2] to initialize. Since i didn’t change gcc version during compile root5.14 and 5.18, I guess root adds more requirement in the code.
