repeatable crash generating two column index

I'm working the example in "Postgresql Developer's Handbook", page
218. I can create an index on a single column no problem, but when I
try to create a index over two columns ->

CREATE INDEX idx_id_perftest ON perftest (id, astring);

the backend crashes every time. I see the following in the logs...

2002-07-03 08:33:29 DEBUG: server process (pid 53454) was terminated by signal 11
2002-07-03 08:33:29 DEBUG: terminating any other active server processes
2002-07-03 08:33:29 DEBUG: all server processes terminated; reinitializing shared memory and semaphores

I can create/drop a single column index after the crash/recovery no problem.

I am using FreeBSD 4.6, Postrgresql 7.2.1. I'm not including the code
because it's copyright but can forward to a debugger. The code just
generates 10 million columns with an ID, and a random number and
string...

mvh=> select * from perftest limit 10;
id | astring | anumber
