--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
GCC 4.9 and before gave a slightly better error message:
<source>: In function 'void f()':
<source>:8:12: error: no matching function for call to 'X::X(int)'
     new X(0);
            ^
<source>:8:12: note: candidate is:
<source>:2:5: note: X::X(int&)
     X(int&);
     ^
<source>:2:5: note:   no known conversion for argument 1 from 'int' to 'int=
&'=
