New Feature (BUG) with Rad Studio 13

Hi Arnaud,

compiling with new 32Bit Compiler for Release Mode, we get the following Error:

[dcc32 Fataler Fehler] mormot.core.interfaces.pas(8256): F2084 Interner Fehler: C2802

The Reason is:

    TDocVariant.NewFast(result);

With this WorkAround it works:

    var LResult : variant;
    TDocVariant.NewFast(LResult);
    result := LResult;

Yes, you are right.
This is a Delphi 13 bug.
But it was reported, and this ticket is opened on Embarcadero side:
https://github.com/synopse/mORMot2/issues/380

Nice finding the workaround.
It is indeed an inlining issue. Hope they will fix this in their first patch, coming in the next weeks, I hope.

In the meanwhile, I tried to circumvent the issue:
https://github.com/synopse/mORMot2/commit/4be675bc5
Should not change much in terms of performances.

Re: New Feature (BUG) with Rad Studio 13

There's also an issue with compiling mormot 1: [dcc32 Fatal Error] SynMongoDB.pas(6863): F2084 Internal Error: C2802. https://github.com/synopse/mORMot/blob/ … .pas#L6863

Also, due to the new noreturn directive, a warning has appeared: [dcc32 Hint] SynCrypto.pas(6282): H2077 Value assigned to 'ThreadWrapper' never used.

function ThreadWrapper(var P: TThreadParams): Integer; stdcall;
begin
  with P do
    AES.DoBlocks(bIn,bOut,bIn,bOut,BlockCount,Encrypt);
  ExitThread(0);
  result := 0; // make the compiler happy, but won't never be called
end;

You had to add an unnecessary assignment to result in the code to make one compiler version happy, but now a new one has appeared and it's sad...
