Working around “[dcc32 Fatal Error] F2084 Internal Error: DBG3133” or “[dcc32 Fatal Error] F2084 Internal Error: MA1243

Posted by jpluimers on 2017/05/30

Since Google has a hard time searching G+: [WayBackAnyone ever encountered a “[dcc32 Fatal Error] F2084 Internal Error: DBG3133″… – G+ – Jeroen Wiert Pluimers:

Anyone ever encountered a [dcc32 Fatal Error] F2084 Internal Error: DBG3133 in XE8 or newer?

I get it in XE8 version 22.0.19908.869 intermittently on a huge* project when compiling or building.

If it occurs, I have to:

  1. restart the IDE
  2. delete all DCU files
  3. build

Without deleting the DCU files, even a build throws the error after restarting the IDE.

The project never throws an AV while compiling as described in [WayBackQC #127380: F2084 Internal error AV0B8A47D2-R3E1D3CF8-0 when compiling project unless the IDE runs out of memory (which I now resolved with DDevExtensions).

Every now and then on compile it also throws [dcc32 Fatal Error] F2084 Internal Error: MA1243.

For the other error, the same solution applies: if you don’t, then the next one is a [dcc32 Fatal Error] F2084 Internal Error: DBG3133.

Both errors occur during the Linking stage.

*huge as in that I needed DDevExtensions to work around [WayBack] Is there any tool that clears the Delphi memory overhead when a “build all” switches to the next project in a project group? XE8 constantly runs out of memory… – Jeroen Wiert Pluimers – Google+

Delphi XE8 [dcc32 Fatal Error] dcc32_F2084_C2359.dpr(30): F2084 Internal Error: C2359

Posted by jpluimers on 2016/10/05

Fails in Delphi XE8 with a nice [dcc32 Fatal Error] dcc32_F2084_C2359.dpr(27): F2084 Internal Error: C2359

It is fixed in Delphi 10.0 Berlin, but of course a C2359 search does not reveal that as Quality Portal is behind a wall. So for future reference the bug: [RSP-13471] Int64 for loops can generate Internal Compiler Error – Embarcadero Technologies. Thanks +Stefan Glienke for mentioning the issue.

program dcc32_F2084_C2359;

type
  TNumber = Int64; // UInt64; // fails too; other numeric types do not fail. Fails in a unit as well.
  TNumbers = TArray;
  TNumberRange = record
  strict private
    function GetLowerBound: TNumber;
  public
    function Numbers: TNumbers;
    property LowerBound: TNumber read GetLowerBound;
  end;

{ TNumberRange }

function TNumberRange.GetLowerBound: TNumber;
begin
  Result := Default(TNumber);
end;

function TNumberRange.Numbers: TNumbers;
var
  lValue: TNumber;
begin
  for lValue := LowerBound to LowerBound do
  ;
end;

begin
end.

Workaround for Delphi 2010 error Fatal : F2084 Internal Error: AV00434055-RA37CCB72-0

Posted by jpluimers on 2015/09/24

Often in Delphi 2010, you can get an error like this:

C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\Bin\CodeGear.Delphi.Targets(136,3): error : C:\Users\Developer\Versioned\Spring4D\Source\Base\Reflection\Spring.Reflection.pas(1647) Fatal
: F2084 Internal Error: AV00434055-RA37CCB72-0

There is a very simple workaround:

  1. If you are in the IDE: quit the IDE
  2. Delete all .dcu files the project generates
  3. If you were in the IDE: restart the IDE and reload the project
  4. Compile the project again

Note:

Sometimes it pays off back-porting to Delphi 2010: the generated executables are a lot smaller than more recent Delphi versions which can make a huge differenec when uploading many versions of bootstrap binaries to a version control system.

Delphi 2007: reproduction and workaround for “[DCC Error] ….pas(26): F2084 Internal Error: AV21BCE0AC-R00000000-0”

Posted by jpluimers on 2012/07/31

Just in case you come across this error ([WayBackQC 108189):

[DCC Error] CompilerAVUnit.pas(26): F2084 Internal Error: AV21BCE0AC-R00000000-0

I had this error in a really complicated unit that I tried to backport from Delphi XE2 to Delphi 2007 (as there was some non-unicode compliant app that needed this).

I could not find it searching for F2084 Internal Error, so I sat down and trimmed it down to the CompilerAVUnit below.

The workaround is simple: remove the static; from method Outer and it compiles fine.

I will post more details on the static keyword in Delphi in a future blog post. For now I’ll keep it at this: Read the rest of this entry »

When you are bitten by normally having the luxury of a current development environment

Posted by jpluimers on 2011/10/06

Sometimes you are at clients that don’t fully appreciate the luxury of keeping their development environment current.

This case a client still using Delphi 2006, where I promptly ran into a compiler error that was solved 5 years ago: a “F2084 Internal Error: C11919” at the end of the method.

begin
  if RMQResult.Create(CompCode, Reason).IsOK then
//...
end; // [Pascal Fatal Error] MQObjects.pas(668): F2084 Internal Error: C11919

The cause is that the compiler barfs at calling a method on a freshly created record.
The function result is an intermediate, which is not handled correctly (fixed in Delphi 2007).

This is not only for record intermediates: reusing an intermediate like the result of Pred() will crash the compiler in Delphi 2006.

The workaround is introducing a real variable.
This works:

var
  MQResult: RMQResult;
begin
  MQResult := RMQResult.Create(CompCode, Reason);
  if MQResult.IsOK then
//...
end; // compiles fine
