Hi all,
  I have encountered something really strange that I cannot 
figure out.  I am packing a 71x10 array of reals with

pvmfpack(REAL4,array,71*10,1,IERR) and am using

pvmfunpack(REAL4,array,71*10,1,IERR) to unpack the data in

the receiving process.  When I do this, 2 of the elements
in the received array are wrong.  The first incorrect
element is array(1,4).  Even when I only send 1 row of
the array, the (4) element is incorrect.  If I send only
the first 4 elements of the array, the (2) element
is wrong.
  I have isolated the array and removed it from common blocks
and still get the same behavior.  If i break up the array and
send it in two pieces, I still get the same behavior.
  I've tried sending a row or a column at a time (rows give
the same error, columns slightly different).  
  This is all on a single DEC Alpha machine running PVM 3.3.11,
any ideas?
