app terminates after a few mins

I'm using this code to make my processor usage go to 100% (testing something with CPU temp)... the code is random, doesn't make sense anyways, I'm just including it for reference:

VB Code:

Imports System.Threading
Module Module1
    Sub main()
        Dim t1, t2 As Thread
        t1 = New Thread(AddressOf foo)
        t2 = New Thread(AddressOf foo)
        t1.Start()
        t2.Start()
    End Sub
 
    Sub foo()
        Dim i As Integer
        Dim b As Double
 
        Do
            For i = 0 To Integer.MaxValue
                b = (i ^ 2) - i
            Next
        Loop
    End Sub
End Module

I have a p4, 3ghz hyperthreaded, 1gb ram.... I run this and after about 7 mins the program just shuts down without any messages or anything showing up. It just dissapears from task manager. This is a bit abnormal to me and I was just wondering if you've seen something like this happen. I'm running this on winXP btw....

maybe it's because b get's a value that's just too high and an error is thrown? When you're using multi threads this kind of exceptions many of the times aren't thrown up but they still ocurr.

hmm so that has to do with multithreading?
is this something official that multithreaded apps dont throw all the errors?:D cuz it doesnt make sense to me
