This bug was introuduced by the official Patch 2, namely by the stwini-
changes. The buffer in which the partitioning information is read in
(struct hi) was global before and local on the stack now. But the default
stack size is equal sizeof( struct hi). That's why increasing the stack
size of the winchester task will be a fix, too. My fix was very simple,
I just add a simple static before struct hi hi in do_open(). I send this
fix to Frans Meulenbroeks and he has included it into his patch 3. So
I think there should be no problem with the printer device after applying
the 3rd patch. My system is actually running MINIX ST 1.5.10.2 compiled
witch ack.
