Actually I have the freeze on my computer right now. I did this:

gdaltransform -s_srs epsg:4326 -t_srs epsg:3067
30 65
641428.429705435 7211811.30748109 0
31 70
652590.036387019 7770880.82231984 0

Then I tried to close the program with Ctrl-C but it did not close. Now it
does not take any input at all. It may well be that my issue is exactly that
I can't close gdaltransform with Ctrl-C after idle time and perhaps I have
seen the same with cs2cs.

In an earlier test I got this print on my screen, I don't know if it is
related or not:
