--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Reduced to remove the Boost dependency:
class base; // {};
class derived; // : public base {};
void func(base* p);
derived* get();
int main()
{
func(get());
}
d.cc: In function 'int main()':
d.cc:11:13: error: cannot convert 'derived*' to 'base*' for argument '1' to
'void func(base*)'
func(get());
^
For comparison, clang outputs:
d.cc:11:3: error: no matching function for call to 'func'
func(get());
^~~~
d.cc:5:6: note: candidate function not viable: cannot convert argument of
incomplete type 'derived *' to 'base *'
void func(base* p);
^
1 error generated.
