With certain long keys the following code throws AV

  s := StringOfChar('x', 222);
  dict := Collections.NewKeyValue<string,integer>;
  dict.TryGetValue(s, v);

Debugging it it looks like that the HashSynUnicode code is missing a defererence here:

    if l > 255 then // no need to hash too big a content
    begin
      Item := @PAnsiChar(Item)[l - 256]; // hash ending of string
      l := 256;
    end;

It should be PAnsiChar(Item^), the current code hashes the memory at an offset relative to the string reference, not the start of the string content (with strings longer than 127 chars).
