Delphi Internal Error L721

Recently I have been using Delphi 5 on Windows XP and now and again get the error ‘Internal Error L721’ when I try to compile my application. After looking on the net to try to resolve the issue, I thought it might be a lack of memory and there was insufficient memory to compile the application. I tried closing other programs down to release some memory but the problem still occured. I best solution I have found for the compiler error is to either restart Delphi, or do a complete rebuild of the project.
