collect problem

[Ben Sapp]

Hi,  

I have program that crashes when it uses the collect function of the ex
class.  The strange error I receive is:

Not a 32-bit integer: -9223372028264841216

I am able to print both the expression and the symbol I am going to use
for the collect call before hand and all seems fine.    I archived the
symbol and expression just before I knew it would crash and I can look
at the function with viewgar.  However if I make a program that uses
collect on the expression I get the same strange error and the program
exits.    Is this a bug in GiNaC?  Is it a bug in my software?   What
could be causing this?   How can I fix it?   

I have attached the archive file and the source to the program that
reads the archive file.   I did not give the source to the software that
originally produced it because it is a function that is dynamically
linked with another program.(GNU Octave)  

In case my system configuration is important:
[ben at pcben Linux]$ ginac-config --version 
0.6.4
[ben at pcben Linux]$ g++ -v       
Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/2.95.2/specs
gcc version 2.95.2 19991024 (release)
[ben at pcben Linux]$ uname -a 
Linux pcben 2.2.12-20 #1 Mon Sep 27 10:40:35 EDT 1999 i686 unknown

Thanks for any insight.
