With the following test case: Either an invalid argument or abort triggered on
READ depending on datasize.  Initial test case from Dale Ranta Comment #15 of
pr26423.  Seems to trigger for datasize less then 1022.

      program test
      integer,parameter :: datasize = 1020
      dimension idata(datasize)
        idata(1)   =  -1
        idata(  datasize)   =  -2
       write(11)idata
        idata(1)   =  -2
        idata(  datasize)   =  -3
       write(11)idata
        idata(1)   =  -3
        idata(  datasize)   =  -4
       write(11)idata
        idata(1)   =  -4
        idata(  datasize)   =  -5
       write(11)idata
       read(11,end=        1000 )idata
       call abort()
 1000  continue
       backspace 11
       backspace 11
       backspace 11
       read(11,end=        1001 )idata
        if(idata(1).ne.  -3.or.idata(  datasize).ne.  -4)then
            write(6,*)idata(1),idata(  datasize)
            call abort()
        endif
        stop
 1001  continue
       print *, "Read Error."
 1010  stop
      end

This does not fail with 4.0.2 , so it is a regression after all, but farther
back.

------- Comment #2 from jvdelisle at gcc dot gnu dot org  2006-02-26 21:38 -------
It turns out that this bug is related pr26835.  The patch I am about to submit
for review removes the flush from st_read_done added to fix pr26835 and
modifies backspace to do the flush as necessary there instead. (which fixes
case in Comment this PR as well)

It looks like you got it this time. I tried all of the previous tests with good
results and I randomly tested a few hundred different I/O blocks size between 2
and 10000 with out finding any errors.
