Problems debugging STL

[Jose Luis Fernández Díaz]

Hi,

I have:

address@hidden /tmp]$ g++ --version
egcs-2.91.66
address@hidden /tmp]$ gdb --version
GNU gdb 4.18
Copyright 1998 Free Software Foundation, Inc.

address@hidden /tmp]$ uname -a
Linux narcea 2.2.12-20 #1 Mon Sep 27 10:40:35 EDT 1999 i686 unknown

I compile the program:

include <iostream.h>
#include <vector>

int main(void)
{
  vector<int> v1(2);
  v1[0]=1;
  cout << v1[0] << endl;
}


with: g++ -g kk.C and debug it with: gdb a.out :



(gdb) b main
Breakpoint 1 at 0x8048fd7: file kk.C, line 7.
(gdb) r
Starting program: /tmp/a.out 

Breakpoint 1, main () at kk.C:7
7         vector<int> v1(2);
(gdb) n
8         v1[0]=1;
(gdb) n
9         cout << v1[0] << endl;
(gdb) p v1[0]
Internal: Cannot demangle mangled name
`__vc__Ct6vector2ZiZt24__default_alloc_template2b1i0Ui'.


What's the problem ?

Thanks in advance,
Jose Luis.
