This works for me:
Breakpoint 2, testObj () at pr.cc:20
20 std::cout << &obj << std::endl;
(gdb) n
0x7fffffffe450
21 std::cout << &obj2 << std::endl;
(gdb) n
0x7fffffffe440
22 return obj;
(gdb) p &obj
$3 = (testClass *) 0x7fffffffe450
(gdb) p &obj2
$4 = (testClass *) 0x7fffffffe440
I think this was actually a GCC bug, already reported both in gdb
and gcc bugzilla, but I couldn't quickly find the gcc PR.
If you can try a newer GCC (I'm using the Fedora 15 GCC, which is
based on 4.6), please do.
Otherwise, let me know and I will close this.
