           Summary: forward reference of function type alias resets calling
                    convention
           Product: D
           Version: 1.024
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: thecybershadow gmail.com


// == minimal testcase start ==
alias uint DWORD;
MY_API_FUNCTION lpStartAddress;  // <-- comment this line to remove error
extern (Windows) alias DWORD function(void*) MY_API_FUNCTION;
static assert(MY_API_FUNCTION.stringof == "uint(Windows *)(void*)");
// == minimal testcase end ==

The actual calling convention (MY_API_FUNCTION.stringof) is "uint(*)(void*)".
This is from a real-life case (the Windows header project).

For dmd 2.023

alias uint DWORD;
MY_API_FUNCTION lpStartAddress;  // <-- comment this line to remove error
extern (Windows) alias DWORD function(void*) MY_API_FUNCTION;
static assert(MY_API_FUNCTION.stringof == "uintWindows  function(void*)",
MY_API_FUNCTION.stringof);

Subtle and disastrous bug, raising severity.

Created an attachment (id=465)
evaluate forward referenced alias in correct scope

The forward reference to the alias causes its semantic analysis to be run from
the scope of the variable declaration, omitting the "extern(Windows)"
attribute. The patch uses the scope of the symbol (which happens to already
exist) instead of the current scope.

The patch also fixes the bad spacing "uintWindows".

You're a legend! This was on my list of ten most worst bugs in DMD.
