[Lingot-devel] lingot 0.8.0 hangs

[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.
