Bug 11696 – C++ incorrect static member mangling

class.d: --- class Expression; struct Loc { } extern(C++) class CallExp { static CallExp *factory(Loc, Expression, Expression) { assert(0); } } class.cc --- class Expression; struct Loc { }; class CallExp { public: static CallExp *factory(Loc, Expression*, Expression*); }; CallExp *CallExp::factory(Loc, Expression*, Expression*) { } G++ produces the following mangled symbol for factory: _ZN7CallExp7factoryE3LocP10ExpressionS2_ Whereas cppmangle in the dfrontend produces: _ZN7CallExp7factoryE3LocP10ExpressionS1_
