Rangecheck triggers on overflow but Overflow check does not trigger, moreover -CR option generates range check code while $OBJECTCHECKS directive doesn't

Version: main branch (3.3.1-9981-gd5d97169), x86-64 Linux

Consider this code:

program project1;

{$RangeChecks On}

var
  A, B: UInt32;

begin
  A := $FFFFFFFF;
  B := 1;
  A += B;
  WriteLn(A);
end.

This should (IMHO) not trigger a range check but an overflow check instead.

• it will trigger a range error if range checks are enabled, either with {$RANGECHECK ON} or with -Cr
• it will NOT trigger an error if overflow checks are enabled, neither with {$OVERFLOWCHECKS On} nor with -Co.

Even more confusing is it will also trigger with -CR, when I enable -CR option on the commandline it will generate code for range- and overflow checks and trigger a range error while when enabling the same with the {$OBJECTCHECKS ON} directive instead it won't trigger.
