Description Jakub Jelinek 2004-05-27 15:17:22 UTC 
C { dg-options "-g -fno-globals -Wno-globals" }
      subroutine a(i)
      implicit none
      integer i
      i = 0
      return
      end
      subroutine a(i)
      implicit none
      integer i
      i = 0
      return
      end

It seems that -fno-globals option happily allows compiling source which will
not assemble later on and with -g causes ICE.

I can confirm this with almost all compilers but I do not know if this is ever going to be fixed in a 3.4.x 
compiler as g77 is dead (removed) on the mainline replaced by gfortran.
Comment 2 Andrew Pinski 2004-05-27 20:11:15 UTC 
I should note that -fno-globals is saying that you do not want any globals at all but then you are using 
a global so this is invalid code and you are also saying do not check for globals (-fno-globals).  Since I 
do not think this option is useful for gfortran at all.  Closing as will not fix.
