Original from Karel Volný:

Hi,

I've tried the new version today, and I have a problem - the
program hangs. It seems there is some problem allocating input
buffer, as "buffer=0xffffffffffffffff" does not look sane to me
(in fact, I'd expect segfault with such value). But I can't find
any problem with the corresponding malloc or anywhere ...

Please, could you take a look?

K.
