The fpc-3.0.4-0.rc1.x86_64.rpm does not work on Fedora 21 x86_64:

Yes, but make sure it is RPM/fedora in the title, so the fedora maintainer sees it.

A linker version would also be nice.

Where is the Mac OS X version?

Many thanks Marco and the rest of the FPC team. I did some testing today for a couple of hours with the 64-bit FreeBSD 10.x release candidate and so far it seems to be working without a hitch. I'll continue using it and report any issues that might crop up.

Regards,
Graeme

I've been using FPC 3.0.4 for a while now under 64-bit FreeBSD. I've noticed that a tracelog with line info generated by the applications are not working as they did in FPC 2.6.4. I then tested with FPC 3.0.2, and it seems broken there too (I've never really used FPC 3.0.x for production code yet). The problem - there is no line information.

For example:

****** Compiled with FPC 3.0.2 or FPC 3.0.4 - no line info

[t1]$ ./project1
THook did it
Heap dump by heaptrc unit
4 memory blocks allocated : 115/120
2 memory blocks freed : 67/72
2 unfreed memory blocks : 48
True heap size : 1146880 (32 used in System startup) True free heap : 1146496
Should be : 1146544
Call trace for block $00000008007390C0 size 32
Call trace for block $00000008007310C0 size 16

****** Compiled with FPC 2.6.4 - not the line info pointing to ****** the originating point of a memory leak

[t1]$ ./project1
THook did it

4 memory blocks allocated : 99/104
2 memory blocks freed : 51/56
2 unfreed memory blocks : 48

The complete sample application is here:

=======================[ project1.pas ]============================
program project1;
{$mode objfpc}{$H+}
{$interfaces COM}
type
    IHook = interface
      ['{4BCAEDD8-92D8-11E7-88D3-C86000E37EB0}']
      procedure DoIt;
    end;
type
    THook = class(TInterfacedObject, IHook)
    private
      procedure DoIt;
    end;
    procedure THook.DoIt;
    begin
      writeln(ClassName + ' did it');
    end;
type
    TBaseClass = class(TInterfacedObject, IHook)
    private
      FHook: IHook;
      property Hook: IHook read FHook implements IHook;
    public
      constructor Create;
      destructor Destroy; override;
    end;
    constructor TBaseClass.Create;
    begin
      FHook := THook.Create;  // FPC 2.6.4 reports a memory leak here
    end;
    destructor TBaseClass.Destroy;
    begin
      // nothing to do here
    end;
var
    base: IHook;
begin
    base := TBaseClass.Create;
    base.DoIt;
    base := nil; // just to see if it helped with the memory leak - it
doesn't
end.
