Could somebody (from Apollo) tell me why the following
crashes Apollo's Unix (csh and Bourne):

Compile these two little routines:
==========================================
      subroutine c1
      common // b(5)
               
      print *, 'c1: b(1)= ', b(1)
      print *, 'c1: b(5)= ', b(5)

      call c2

      return
      end

      subroutine c2
      common // c(5)

      print *, 'c2: c(1)= ', c(1)
      print *, 'c2: c(5)= ', c(5)

      c(1) = 111
      c(5) = 111

      return
      end
==========================================

Compile this little main program:
==========================================
*
*-- main program to intialize static data
*
      common // b(5)

      print *, 'blank common initialized'

      stop 
      end
==========================================

Make an installed library from these three
routines:
==========================================
#! /bin/sh

bind -b foo.inlib -<<\!
main.bin
-looks -all
-marks -all
-allmark
c1.bin
!
==========================================

Install the library (in DOMAIN/IX Unix):
==========================================
inlib foo.inlib
==========================================

And flash, super crash.

Note, in the Aegis (/com/sh) this works fine.
BTW, the contents of the  two little routines
does not matter. The only problem is the main program that 
initializes the static data. Remove the main program 
(and change the routine c1 so it uses a parameter to get
its value for b) and everything works well. 

I am running SR9.2.4 and inprocess is set in the csh.

Is this a BUG or a feature???

Cheers,
    Fons Rademakers
