Run-time errors

[Mark Chimley <M.Chimley@bristol.ac.uk>]

I am running Debian Linux on a PC and compiling using gcc and version
2.0.1 of the pari library. I have the following code:

pari_init (500000, 1000);
Gen n = 0;
n = nextprime (n);

At run-time this gives "Incorrect type in gceil". I have also tried
using isprime (n), which gave "Segmentation fault". I get the impression
that something is fundamentally wrong here, since this is the first time
I have tried to compile anything after installing the software.
Alternatively, I might be missing something obvious. Any
clues?

Mark.
