uuid c function contrib

Hi,

I've written some PostgreSQL C functions which expose the functionality
of Theodore Ts'o's UUID library.  I need to add a few sanity clauses
here and there, but working (mostly) code can be found here:

http://www.yellowbank.com/code/PostgreSQL/uuid/

I have one problem.  My y_uuid_time function works on my laptop
(Kubuntu/Dapper), but not on another box (Debian Sarge).  PostgreSQL
8.1.4 in both cases.

When it works, it looks like this:

rpeterso=# select y_uuid_time( y_uuid_generate_time() );
     y_uuid_time
---------------------
 2006-10-17 14:29:34

When it doesn't, it looks like this:

rpeterso=# select y_uuid_time( y_uuid_generate_time() );
server closed the connection unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

I've been staring at my array bounds so hard it's giving me headache.
If anyone can identify what might be wrong, I'd greatly appreciate it.

Best.
