Fowarded from one of our researchers:


I have a problem with the Risc f77 compiler.  the following program will
not run:

      program test
      call sub  ('sub')
      call sub1 ('sub1',a1)
      call sub2 ('sub2 entry',a2,a3)
      stop
      end
c
      subroutine sub (c0)
      character*(*) c0,c1,c2
      print *,c0
      return
      entry sub1(c1,a1)
      a1 = 1
      print *,c1,a1
      return
      entry sub2(c2,a2,a3)
      a2 = 1
      a3 = 1
      print *,c2,a2,a3
      return
      end

it gives essentially a segmentation fault.  i tried turning off the 
optimizer and other options but nothing worked.  the above program
construction is valid in fortran 77, and the same program runs on our vax
under either f77 or fort commands.

if this construction is strictly not allowed on risc then the
installation of the our code will be set back at least a month
and probably longer to allow for reorganization of the code!

----

any ideas?
anybody we can talk to?

I understand there is a new release coming - we can get permission to use
a beta version if it will fix this.

thanks again,

hurf
