Hi Volker,

I today have examined the problem. I mailed you before that I can 
reproduce the problem, using int, and that using double the problem does 
not occur. That is (alas) still the case. So the problem has not been 
fixed in 1.50.

I hope the problem can be fixed and then the first version it might get 
in is 1.51, so if you are considering upgrading, w.r.t. this problem it 
is not worth going to 1.50.

I understand the problem, don't need more reproductions currently (I'll 
ask if I need).

A possible workaround is going to double. You can even go to double 
temporarily, only for this operation, and after that convert to back to 
int. But of course that is not ideal and sometimes not feasable.
