[Bug fortran/42422] New: Error in Fortran list directed input

[palmtag5 at yahoo dot com]

An error occurs when arrays are read from the input using list-directed 
input that uses a repeat(*) before a record terminator (/).
The repeat is ignored.

For example, reading an integer array dimensioned 10
     integer :: imatrx(10)
    ...
     read (*,*) imatrx

will give the wrong results when the input has a repeat before the record
terminator

     1 2 3 4*5 /

Will read in the values as "1 2 3 5 x x x x x x"
instead of "1 2 3 5 5 5 5 x x x"

Full example:
      program test2
      implicit none
      integer :: imatr(20)
      imatr=0
      write (*,*) 'Enter 20 integer values:'
      read (*,*) imatr
      write (*,*) 'results:'
      write (*,*) imatr
      end

With input:

 1 2 3 4*5 /

Hmm, I cannot reproduce this with newer gfortran version. Using 4.2.1 I also
get:
  1 2 3 5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
however, already with 4.3.4 [gcc-4_3-branch revision 152973] I get:
  1 2 3 5 5 5 5 0 0 0 0 0 0 0 0 0 0 0 0 0
which looks OK.

Can you try a newer GCC version? Current stable version is 4.4.2; previous
stable version is 4.3.4 (which is slightly but sufficiently newer than your
4.3.2). And the current developer version is 4.5, which is currently in stage 4
(only regression fixes) and will be released beginning next year. [Personal
educated guess: end of February.]

See also http://gcc.gnu.org/wiki/GFortranBinaries for obtaining a new binary.

I can confirm this works on all supported versions.

Should we add a test case, then close this bug?

IMHO.  Yes.

A new testcase is pre-approved provided it passes a
regression test. :-)

Thomas, let me know if you want me to do the test case.
