--- Comment #4 from Carl Ponder <cpon...@nvidia.com> ---
Can you please list out the commands more precisely?
I ran these commands in one window:

      module purge
      module load pgi/16.9
      module load gcc/4.8.5
      module load valgrind

      pgfortran -o test03.pgi test03.f90 -O0 -gopt -Mstack_arrays
      valgrind --tool=memcheck --vgdb=full --vgdb-error=0 test03.pgi

Then in the second window I ran these commands:

      module purge
      module load pgi/16.9
      module load gcc/4.8.5
      module load valgrind

      gdb test03.pgi
      target remote | vgdb

      b 77
      c

so far so good. But now:

      print N

gives

      Cannot access memory at address 0x4011a0000000

Why is this? And

      print x(1)

gives

      value being subranged must be in memory

And

      xb 0x4011a0000000

gives

      Undefined command: "xb".  Try "help".
