Hello rubin,

I am working through the bug reports from bug-gdb@gnu.org and I
just got to your message from February 2004.  I apologize for
the five month delay.

I tried your program:

      program equiv
      dimension i1(10),i2(10) 
      equivalence (i1(1),i2(1))
      i1(1) = 11
      i2(2) = 22
      i11 = i1(1)
      i22 = i2(2)
c Put breakpoint at next line before using print in debug
      stop
      end

I compiled this on native i686-pc-linux-gnu, red hat linux 8.0,
with g77 3.3.4 and g77 3.4.1.  The command line is:

  g77 -gdwarf-2 rubin.f

Then I debugged a.out with gdb 6.1.1.  I put a breakpoint on
the 'stop' line and printed the values:

  (gdb) print i11
  $1 = 11
  (gdb) print i22
  $2 = 22
  (gdb) print i1(1)
  $3 = 11
  (gdb) print i1(2)
  $4 = 22
  (gdb) print i2(1)
  $5 = 11
  (gdb) print i2(2)
  $6 = 22

So this works with the current released versions of gcc and gdb.

If you have any questions I'd be happy to help.
