Description Denis Shelomovskii 2016-03-21 18:09:28 UTC 
This code should compile:
---
void f(int); // line 1
void f(int);
void f(int);
void f(int);
void f(int); // line 5

void main()
{
    f(1); // line 9
}
---
main.d(9): Error: main.f called with argument types (int) matches both:
main.d(1):     main.f(int)
and:
main.d(5):     main.f(int)
---

If any declaration is converted to definition the code compiles.
Also note the error message only reports about the first and the last declaration.
