This issue prevents being able to produce debug info if you use DerelictFreeType library, which is a pretty big issue for a number of D game developers. Who knows how many times I've explained this bug. I'd suggest this as a 1.0 blocker.

Why is it a blocker when it is illegal code anyway? (Foo is undefined.)

How about this code?

--- bug.d ---
Foofunc f;
typedef int Foo;
alias int function(Foo) Foofunc;
------

It compiles with dmd -c bug.d, but dmd -c -g bug.d fails with the following:

error: forward reference of Foo

Of course the workaround is to change the code to

typedef int Foo;
alias int function(Foo) Foofunc;
Foofunc f;

Thanks, that's much better.

Here is another example, I'm not sure if it is much better.


struct FT_Var_Named_Style{
T1_Decoder_Callback f;
}

alias int function( T1_DecoderRec decoder ) T1_Decoder_Callback;

What I don't understand is why the code above does not give an "T1_DecoderRec undefined" error. Doesn't the compiler require the types of arguments in function statements to be defined?

This incorrectly compiles without errors. It should give a Foo undefined error. With -g, compiling gives a Foo forward reference error.

  Foofunc f;
  alias int function(Foo) Foofunc;

This correctly doesn't compile. It gives a Foo undefined error.

  alias int function(Foo) Foofunc;
  Foofunc f;

This correctly compiles, but with -g, gives a Foo forward reference error.

  Foofunc f;
  alias int function(Foo) Foofunc;
  alias int Foo;

There appear to be two bugs: the forward reference error, and the mishandling of the argument types in function aliases.
