I'm getting an odd error message in line 366 below (this is part of
variant.d):
../utd/variant.d(366): Error: switch case fallthrough - use 'goto case;' if
intended
But you can see that line 366 already has a "goto case":
switch(id) {
foreach(i,T; ICT!A ) {
static if (is(typeof(*cast(T*) ptr = *src)) ) {
// BUG workaround the string <=>
immutable(char)[] problem
static if((is(T : const(char[])) || is(T :
const(wchar[])) || is(T : const(dchar[]))) &&
T.stringof !=
(typeof(T.init[0])).stringof~"[]" ) {
case (typeof(T.init[0])).stringof~"[]": goto
case;
}
// isImplicitlyConvertible!(T,immutable T) [inlined]
static if( !is(immutable T == T) &&
is(typeof({void fun(immutable(T)){} T f; fun(f);}())) ) {
case (immutable T).stringof: goto case;
}
static if(!is(const(T) == T) &&
!(i==1&&is(typeof(T.init[]))) ) {
case (const T).stringof: goto case; //
THIS IS LINE 366
}
case ( T).stringof:
static if(is(T:Object)) {
if(info !is typeid(T) && info !is
typeid(const T) && info !is typeid(immutable T) )
continue;
}
if (src && ptr)
*(cast(T*) ptr) = *src;
return true;
}
}
Any help is appreciated, thanks
John
