Hi
i have found the problem
views.inc(4318,17) Error: Wrong number of parameters specified for call to
"$copy"
that is not what it says
It has nothing to do with the parameters. FPC generates this message if
no matching callable function is not found for any reason
In this case because "copy" was not public in the record. I can set a
flag [cnf_ignore_visibility] in the compiler
Bye,
Benito

Amazing!
There are two places that call them. compiler/nld.pas and compiler/ngenutil.pas
where it creates the call nodes. There my patch turns them into ordinary
function calls, which can be inlined like any other function call.
This is the "old way" you describe. Why did they do it like this instead of
normal function calls which could be inlined? I suspect one of the compiler devs needs to
explain this because there may be a reason.
Then there is compiler/hlcgobj.pas, which calls initialize/finalize for local
or temporary variables. That appears to happen after the inlining is done.
Perhaps it needs to do the inlining first to know which variables are there,
and afterwards it could not change them anymore.
So the inlining caused extra init/finalize calls? That's not good for sure.
There's already a problem with an extra copy operator being called on temporary
memory which can make or break the feature entirely depending on your usage.
