I installed that so I could compile as win32 for comparison. The test program works if compiled with Lazarus for win32 but not win64 >While in lazarus open agg_rasterizer_scanline_aa.pas, go ro line 611 press Ctr >and click on ptrcomp.

I was able to follow this and get to the comment in agg_basics, I read the comment that indicates some difference and possible problem with pointers on win64 but I don't know what I can do about it and why you are able to cross compile for win64 and it works. I wonder if this is an issue with Freepascal 3.0.2, and aggpas hasn't been fixed for it yet and I need to use Freepascal 3.0.1 to get it to work?
