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


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.
