Lucia is working on

return the lowered expression. In the code below

getFuncTemplateDecl(tidSymbol); // returns nil
and the compiler crashes when it hits this line.

//  extern (C++) final class TypeidExp : Expression @ dmd-> 
expression.d

 override Expression semantic(Scope* sc)
    {
        auto tidIdentifierExp = new IdentifierExp(loc, new 
Identifier("__typeidImplT"));
        auto tidSymbol = new Dsymbol(new 
Identifier("__typeidImplT"));

        auto tidDeclaration = getFuncTemplateDecl(tidSymbol);
        auto tidExp = new TemplateExp(loc, tidDeclaration);
        auto callExp = new CallExp(loc, tidExp);

        return callExp;
    }

Any help would be appreciated.


Thanks,
