--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is a pedantic error.
clang errors out with:

<source>:14:12: error: chosen constructor is explicit in copy-initialization
    return {};
           ^~

With -pedantic-errors GCC does error out:
<source>: In function 'foo get_value()':
<source>:14:13: error: converting to 'foo' from initializer list would use
explicit constructor 'foo::foo(const char*, uint8_t)'
     return {};
             ^
<source>:14:13: note: in C++11 and above a default constructor can be explicit


So I don't know if there is a bug to be fixed here or not.
