I'm opening a few files as direct i/o and sequential 
i/o and for one of them I get a status_error.  This
occurs (as best I can figure out) when the passed
file pointer is non-null (so it assumes the file
pointer refers to an already open file).

I used gdb to trace this problem, and presto! The
error goes away.  So, my program runs fine in gdb
(I just enter the debugger and type "run.")  But
running normally, it always gets that exception
raised.

Are there any suggestions on how I can

1) duplicate the error in gdb so as to find out
why this exception is being raised,

2) eliminate this error all together?

Thanks in advance.
