[Bug libfortran/26464] New: Runtime I/O error/invald argument on READ

["jvdelisle at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

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
