Hi,
In call stack window I had seen something like:

 std::_Rb_tree, std::_Select1st >, std::less, std::allocator > >::_M_end()	C/C++

std::_Rb_tree, std::_Select1st >, std::less, std::allocator > >::lower_bound()	C/C++

>	std::map, std::allocator > >::lower_bound()	C/C++

std::map, std::allocator > >::operator[]()	C/C++

main()	C/C++

I have selected third line. The code was exactly like yours:

      iterator
lower_bound(const key_type& __x)
{ return _M_t.lower_bound(__x); }

On 127 line of stl_map.h there is a declaration like:

      /// The actual tree structure.
_Rep_type _M_t;

I checked “GDB Session” and used command which had caused error before:

-data-evaluate-expression "(void *)((std::map, std::allocator > >::_Rep_type::_Link_type)0x0)->_M_left"

Same error was still appearing:

No type "_Rep_type" within class or namespace "std::map, std::allocator > >".

Moreover I have found another errors

-var-create - * "_Rep_type"
mi_cmd_var_create: unable to create variable object

I am attaching whole log to this post.

Edit.
I have attached log for simple project. Previous was based on my current project.

Hi,
I am using gcc (GCC) 4.4.6 20120305 (Red Hat 4.4.6-4) (from Scientific Linux)
and gdb 7.5.1.

I compiled that version of GDB myself, but I have checked also GDB from my distro’s rpm repository – GNU gdb (GDB) Red Hat Enterprise Linux (7.2-56.el6). Same situation has occurred.

GDB Session window contains:

No type “_Rep_type” within class or namespace “std::map, std::allocator > >”.

Hi, I think that I have similar problem with VisualGDB 3.0
What information should I see while debugging std::map container? I have seen something like that (screenshoot attached) , but where are the keys/values? I was hoping to see something like a dictionary in C#.
