Adjust some more code that was depending on the function and delegate calling conventions being equal. There's also an instance in `tango.text.convert.Layout` that should be adjusted: {{{ Index: tango/text/convert/Layout.d =================================================================== --- tango/text/convert/Layout.d (revision 4578) +++ tango/text/convert/Layout.d (working copy) -660,8 +660,12 @@ case TypeCode.STRUCT: auto s = cast(TypeInfo_Struct) type; - if (s.xtoString) - return Utf.fromString8 (s.xtoString(p), result); + if (s.xtoString) { + char[] delegate() toString; + toString.ptr = p; + toString.funcptr = cast(char[] function()) s.xtoString; + return Utf.fromString8 (toString(), result); + } goto default; case TypeCode.INTERFACE: }}}
