Summary0031971: Internal error 2011031501
DescriptionIn a large project (10KLoc + third party components) I get "Internal error 2011031501" in compiling, when I modify data structure in type sections of units. If I delete lib directory and then I compile again, I have no errors.

I have reduced my program to reproduce errors in a smaller source code. In the attached archive there is also a third party library TEvsSimpleGraph (https://sourceforge.net/projects/evssimplegraph/) that I used with some little modifications in my original project.

Thanks!
Steps To Reproduce- Lazarus Version:
    . Version #:1.6.4
    . Date 2017-02-27
    . FPC Version: 3.0.2
    . SVN Revision: 54278
    . i386-win-win32/64

I just got that as well:

> xquery.internals.protectionbreakers.pas(158,5) Fatal: Internal error 2011031501

I had not made a change in that file. I was changing types in other files though, interface and implementation only types.
