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;

  Function GetLangType:string;
  Function GetDescription:string;
  Function GetStructure:TIniFile;

End;




TLanguages_Controller = Class

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

If i creating clear default VCL Application without any code, it gives this error too...Russon
In earlier versions of Delphi the file name had to match the unit name. In your example above they differSklar
I've tried to doo they same, but its not helpingRusson
This is a compiler bug. You need to submit a QC report.Lockhart
If Delphi gives you any error that includes Internal Error: AV you must restart the IDE because the internal state has been compromised by an access violation.Specific
Your question mentions Delphi 2010, but the tags Delphi XE3. Which version does this happen in?Specific
Try disabling any (and all) 3rd party component packages and/or extensions (experts) and restart the IDE. After that, try the same thing again (with new VCL application). Some component property editors are known to cause this kind of problems.Entablature
I solved this problem, by removing my UNIT and placing its code to the main UNIT. I Guess i need to reflesh my Delphi to new XE4 :)Russon
I got this Delphi BUG too while compiling a unit. Restarting Delphi and deleting the DCU files for the project helped.Fleda
We are plagued again by this, under Delphi 10.4 and Delphi 11Fleda

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.

enter image description here

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?)

I also had this problem (in Delphi 10 Berlin). It started shortly after I changed the name of a component in a frame. It also seemed very persistent. However I found the by right clicking the project and selecting 'Clean' followed by 'Build' solved the problem.

I had this issue with my system drive's memory less than 300mb left. It was especially choking in the cache folder. Prior to this error I had a sensible error (fatal error DBG) when I was attempting to recurse already async functions into a larger async function in a big multi threaded application. The compiler just gave up!(perhaps for circular references and too many subfunctions of a function) The two errors may not be related. But after freeing the system drive to about 2 Gigs upon restart and correcting the above mistake, I did a clean then it compiled just fine.

In my case, the solution for the F2084 error code was to change the encoding from ANSI to UTF8.

In my case, I made several packages that related one to another, and all were built as design and run time packages. But one day, I changed some of them to run-time only packages. After that I experienced this kind of error. It took me hours to realize that I should rebuilt all other related packages. After doing that, the error was away eventually.
