[Bug libfortran/14904] New: [gfortran] INQUIRE returns incorrect LASTREC on multiple writes to DIRECT, FORMATTED units.

[Bug libfortran/14904] New: [gfortran] INQUIRE returns incorrect LASTREC on multiple writes to DIRECT, FORMATTED units.

[bdavis9659 at comcast dot net]

>From NIST test FM912.FOR.

When more than one record is written to a direct access formatted unit with one
write statement, inquire should increment LASTREC to reflect the number of
records written.  Currently, it assumes one write = one record written, which is
wrong.

Small example :

       OPEN(UNIT=10,ACCESS='DIRECT',FORM='FORMATTED',RECL=120)
 100   FORMAT(I4)
       WRITE(UNIT=10,REC=1,FMT=100)1
       INQUIRE(UNIT=10,NEXTREC=J)
       PRINT*,J
 200   FORMAT(I4,/,I4)
       WRITE(UNIT=10,REC=2,FMT=200)2,3
       INQUIRE(UNIT=10,NEXTREC=J)
       PRINT*,J
       END

$ gfc inquire.f
$ ./a.out
           2
           3
          ^^^ 
         should be 4

$ g77 inquire.f
$ ./a.out
 2
 4
