Wrong value used

just dave has asked for the wisdom of the Perl Monks concerning the following question:

Hello monks !
I have a nice program that runs well, that is untill I've added a a small piece of code...

my $firstValue = getField($filename,$fieldName,$lastValue);
my $secondValue = 

getField($secondFileName,$secondFieldName,$lastValue);
my $sumValue = $firstValue + $secondValue;
$hash_of_oids{$request->getOID()}->{'lastValue'} = $sumValue;

$request->setValue($fieldtype, $sumValue);
[download]

Now, my first problem is that my error does not allways happen !! but when it does I get this reply:

 Non-integer value passed to setValue with ASN_INTEGER: type was 6
[download]

nNow, the getField metho returns integers since I use it a lot before this part, moreover, it also prints the numbers ! so I know that $firstValue and $secondValue are returning the correct values.

So, my guess is that $sumValue for some reson is no longer an integer, and that's why the setValue throws this error

but why ?
please help !
Thank you all
Dave

I think it should be somewhat obvious that $sumValue must be integral unless $firstValue and $secondValue are not ... or if their sum is too high to be represented in your native integer types. So, I'd suggest some debugging techniques, such as printing out the $firstValue and $secondValue before setting $sumValue, to make sure they are what you think they are, and to check if they are about to wrap the native integer type for your platform. e.g., if you're using 32-bit perl, chances are that the maximum integer is about 4 billion (232-1), while if you're using 64-bit perl, or 32-bit perl with use64bitint defined, the maximum is about 4 billion squared (264-1). Of course, I'd also check what $sumValue was right before sending it to setValue. Never hurts to double-check.	[reply]

What's the value of `$fieldtype`? Is it the 6 that your error message implies, or does that come from somewhere else? The intelligent reader will judge for himself.
