GDB problems

[Paulo Henrique Baptista de Oliveira <baptista@cos.ufrj.br>]

	Hi Debian users,
	I have some problems with gdb. Bellow I put the error that occurs when I
try to insert a breakpoint using gdb:

baptista@jaca: /home/IA/baptista$ more teste.c
#include<stdio.h>
void main()
{
        int i=1;
        printf("%d", i);
}
baptista@jaca: /home/IA/baptista$ gcc -g -o teste teste.c
baptista@jaca: /home/IA/baptista$ gdb teste

	What is wrong?
	The version of my gdb is of 4.17.199812.
	Have a nice day,		Paulo Henrique
