Free Pascal IDE, Runtime error 4216927?!

Rick314:
See the 2 attached images and test code below. Between the two images is a "Step Over" (F8 in the IDE). Prod64 : QWord (64-bit unsigned) has value 3618239625 = $00000000d7a9f489. I want to put the 32 LS bits into TempDivIntoIt : Longint (32-bit signed). Executing the test code below produces the desired output "3618239625 -676727671", but the single-step in the IDE produces Run Time Error 4216927, Error Address $00000000, loss of Watch Window values, and what appears to be a messed up call stack.

How do I to interpret these results?

What should my path forward be? (Bug report? Workarounds? Debugging suggestions? ...)

program bugtest;
var
TempDivIntoIt :Longint;
Prod64 :QWord;
begin
Prod64 := 3618239625;
TempDivIntoIt := Longword(Prod64);
writeln(Prod64, ' ', TempDivIntoIt);
end.

I don't use this IDE, but based on the call stack in the second image, it is a range check error (fpc_rangeerror). The error message is vague. The error happened because of the typecast Longword(Prod64). A proposed solution is to bypass the check at this point:

--- Code: --- {$Push}
{$RangeChecks Off}
TempDivIntoIt := Longword(Prod64);
{$Pop}

--- End code ---

Thank you engkin. Your suggestion allowed me to go forward and continue what I was doing.
