I tried the sample program on NetBSD 1.4.2, it runs to completion-
the final output being roughly a 4GB file- 4095997952 bytes. I'm still
impressed with how fast/well 1.4.2 + UW SCSI performs.  It only took
a matter of seconds to run this program.  ;)

I can put the a.out up for FTP if you want to run it on your box to
see if it's a compiler/link problem with your tree.

I'd also look into any possible ulimit or shell var/quota set as well.

Warmest regards,
Steve Paul
