g77 bug Alpha/Intel, LEN and // on WRITE statement



 I tried to Email this from my work place but got an error message that
our server was on some list as not being secure against spammers...
So, I'm sending this from my home Email. Please send any response to
both dave@vcnet.com and dave@psrv.com, thank you.


Dear Sirs:  


I believe I have discovered a problem with g77 on both Alpha and Intel
platforms
Alpha -- egcs-2.90.29
Intel -- egcs-2.91.66

The problem involves using the LEN intrinsic for string indexing:

      PROGRAM CONFIGURATION
      CALL LECTURE_PARAMETRES ('/home/mine/tmp/' )
      END

      SUBROUTINE LECTURE_PARAMETRES(CHEMIN_COURANT )
      CHARACTER CHEMIN_COURANT*(*)

      character*(100) heap__

      CHARACTER CHEMIN
      EQUIVALENCE (CHEMIN,HEAP__)
      INTEGER CHEMIN_

      CHARACTER A1*500

      CHEMIN(1:LEN(CHEMIN_COURANT)) = CHEMIN_COURANT

!  doing write(*,*)chemin  works ok too
! this does not work

      WRITE (*, *) ':'//CHEMIN(1:LEN(CHEMIN_COURANT))//
     1   ':'

! this works
      A1 = CHEMIN(1:LEN(CHEMIN_COURANT))
      j6 = len(chemin_courant)
      WRITE (*, *) ':'//A1(1:J6)//':'

      END


Output:

 :/h@×ûÿ¿×î
 :/home/mine/tmp/:


When a temp is introduced, the expected results are achieved. Without the
temp,
there is garbage.

Thanks in advance.

Best Regards,
 David
