Delphi F2084 Internal Error: AV07953449-R26D7474C-0

delphidelphi-xe3

In my project, i'm trying to connect one more UNIT, named Lang_Unit.pas with some classes and procedures, but, while compiling the Project, Delphi gives unknown error called "[dcc32 Fatal Error] Lang_Unit.pas(5): F2084 Internal Error: AV07953449-R26D7474C-0".
And the point is that, what if i will close my project, or remove this connected UNIT, error is not getting away.
And if i will create clear default VCL Application, its still gives this error.
And only when i'm restarting my Delphi 2010, error is getting away.
But, if i will try to edit something in the code, this error is comes again…
What is problem ? Everything was works fine, im not touched nothing.
I've just turned off my PC, then after some time turned it ON and opened my Project and edited my code, then i see this error…

If Its will help, here is my Lang_Unit.pas code :

unit Languages_UNIT;

interface

Uses
  System.Generics.Collections, IniFiles;

Type
TLanguages_List = Class

  private
    LangType:string;
    LangDescription:string;
    LangFile:TIniFile;

  public
  Constructor Create(LType,LDes:string; LFile:TiniFile);
  Function GetLangType:string;
  Function GetDescription:string;
  Function GetStructure:TIniFile;

End;




TLanguages_Controller = Class

  public
  Function GetStructureByType(RequestedType:string; LangList:TObjectList<TLanguages_List>):TIniFile;

Best Solution

Internal error means that the compiler itself is in a 'confused' state.
The way to get out of this is to:

Save your code in a safe location for later reference.
Restart Delphi
Revert the source code to the last known good state by undoing your last edits, or by loading a temp save file.

You can find the previous files in the _backup folder.

backup files

Make sure to set file type to any file.

In order to have Delphi generate a save file upon compilation you need to enable autosave

enable autosave

It's a good idea to have Delphi keep more than the default 10 saves. I like to set it to the max: 90.

Just keep restarting Delphi, and compile a previous version, until the internal error goes away.
Then you just recreate the code in a slightly different manner. (You did save the original code right?)
