In Delphi WideString is not reference counted at all. The layout of the

Normally I would aggree with you, but as far as I can see, PWideChar is
also an automated type. (If not then large parts of the variant-code in
the RTL has to be rewritten, and probably alsoe the wstrings.inc file)
From wstrings.inc:
WideString is defined as a 'silent' pwidechar :

Hi all,
the bug-report on the website doesn't work, so I write a mail:
If you assign a widechar to a pwidechar, the refcount isn't
increased. This construct is often used in the variants-code, which is
allowed, according to the comments at the top of wstrings.inc.
An example:
Program test;
var
