Bug in "sys.settrace" ??

I use sys.settrace in my console application to stop any endless loop
but in the following loop:

a = 0
while 1:
	a = a + 1

the trace function is only called 4 times, but in code 

a = 0
while 1:
    a = a + 1
    print a

the trace function is called infinite times. So i assume that there is
a bug in the first case. I think that the system assumes that it must
not call the trace function again because it is always the same line
number, and the optimizer removes the "while 1" line.
