           Summary: Variadic templates and auto return types don't work
                    together.
           Product: D
           Version: 2.017
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: dsimcha yahoo.com


It seems that one cannot use both variadic templates tuple parameters and auto
return types in the same template function.  Consider the following functions:

/*If instantiated with any of several types I tried, compile time error: 
Assertion failure: '0' on line 847 in file 'glue.c'*/

auto foo(T...)(T dummyInput) {  
    int i = 1;
    return i;
}

//Works.
int bar(T...)(T dummyInput) {
    int i = 1;
    return i;
}

//Works.
auto baz(T)(T dummyInput) {
    int i = 1;
    return i;
}

Adding ice-on-valid-code keyword, now that I realize what that stands for.

Bug 854 is very closely related to this and has had a patch for a while that
probably fixes this one, too.  Please apply.

This one missed the changelog somehow.  Please update.  Anyhow, thanks for the
fix.
