This SCO program I am running allows me to pipe my reports out to
any program. I have to compile it into the database code, which is not
open.  I am piping to a printer but the program crashes.  

It works fine if I just pipe it to a shell script like this one;

cat $1 > ~/printfile

Then I can go "cat ~/printfile | lp -dlj -s"
and it prints fine.

But for some strange reason, if I expand the program to

cat $1 > ~/printfile
cat ~/printfile | lp -dlj -s

the program crashes,
with bad system call - signal 12

If I try and pipe it directly to the print it crashes also.

It doesn't _always_ crash either.

The only work around I can think of, it running a cron that is looking for
files to print every 5 seconds. 

I've tried a number of nohups and background type & which doesn't seem
to help.
