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.

Regards, Barend
