The idea, as I understand it, is to supply a bit mask of where the pointers
are. For me, the difficulties are:
1. distinguishing real pointers from might-be-a-pointer (such as you might get
from union { int a; void* p; }).
2. large static arrays, large structs/classes, structs with large static array
members, etc.
The amount of static data dedicated to such bit arrays could get very large.
I see two solutions:
1. if it is case (1) or (2), give up for that type and revert to the current
method of scanning that object
2. devise a 'state machine' instead that the gc executes for a type. The state
machine has instructions like "advance n bytes to the next pointer" and "the
next pointer is ambiguous" and "execute the following sequence n times."
I don't see an obvious choice which is better.

On trunk dmd, this code cannot compile because of fixing bug4499.
import std.algorithm;
struct S
{
@disable this(this){}
~this(){}
}
void main()

Test case:
-
import std.stdio;
struct S {
ulong a;
alias a this;
}
void main() {
writeln(S.init);
}
-
As of 2.052, this code generates compile-time error with

When emptying a hash table, rehash it and fill it, an error occure.
Code sample :
void main()
{
string[ string ] test = null;
test[ "test1" ] = "test1";
test.remove("test1");
test.rehash;
test[ "test3" ] = "test3";
}
Result:
Error: Interger Divide by Zero

A simple patch is to replace that 'const' with 'immutable'.
