(gdb) tb 8
Breakpoint 1 at 0x10550: file tmp.c, line 8.
(gdb) run
Starting program: /users7/philipj/tmp/a.out

(gdb) p A
$1 = {1, 2} <<<< can see whole array ok
(gdb) p A[0]
Cannot access memory at address 0x0. <<<< but not individual elements
(gdb) p A[1]
Cannot access memory at address 0x1. <<<< but not individual elements
(gdb) quit
The program is running. Exit anyway? (y or n) y
get same behaviour with -gstabs+, -gdwarf & -gdwarf-2
