Description:

Overflow checks and range checks don't get applied to Integer or PtrUInt in the 64bit compiler.

{$MODE OBJFPC}
{$OVERFLOWCHECKS ON}
{$RANGECHECKS ON}
program test;
uses exceptions;  
var I, J: PtrUInt; // try also with Integer or Cardinal; compare with Byte or Word
begin
   try
      J := 1;
      Writeln(0, ' ', J);
      for I := 1 to 65 do
      begin
         J := J shl 1;
         Writeln(I, ' ', J);
      end;
   except
      ReportCurrentException();
   end;
end.

Additional information:

I got downstream reports that with the 32 bit compiler, you do get range checks for Cardinal, at least.
