The output should be like the below:
This is the behavior expected, however it is on FreeBSD7.1 and the gdb on Linux behaves exactly the same unless on the latest version of GDB linux port introducing any kind of gdb-local environmental variable masking the next default. This might be the latest feature. Without this I don't find any reason (no doubt on the GDB code unless you compiled a tweaked source of it to install the same).
Look the release note of the GDB version you are using and try to grep for next to get better insight on the environmental variable, if any.

Which is better??

Hi All,
I wanted to know if there is a core file generated and I am not sure for which Binary it is generated .
Can I use gdb to debug the core file ?
Thanks. (1 Reply)
Hi All,
I am trying to execute a binary and it is giving Segmentation Fault.

dcons
DCONS(4) BSD Kernel Interfaces Manual DCONS(4)NAME
dcons -- dumb console device driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
options GDB
device firewire
device dcons
Alternatively, to load the driver as a module at boot time, place the following line in your kernel configuration file:
options GDB
and in loader.conf(5):
dcons_load="YES"
DESCRIPTION
The dcons device is a simple console device which just reads from and writes to an allocated buffer for input and output respectively. It is
of no use by itself and it is supposed that the buffer is accessed via a bus like firewire(4) or kvm(3) for interaction.
The buffer consists of 4 channels. There are 2 ports, one for the console TTY and another is GDB port, then each port has an input channel
and an output channel.
FILES
/dev/dcons
/etc/ttys
EXAMPLES
If you want to run getty(8) on dcons, insert the following line into ttys(5) and send a HUP signal to init(8) using kill(1).
dcons "/usr/libexec/getty std.9600" vt100 on secure
Once the fwohci(4) device is initialized to allow physical access, the buffer can be accessed from another host via a firewire(4) bus using
the dconschat(8) application. See dconschat(8) for more details.
If you want to use dcons(4) as a gdb(1) port, add the following line into loader.conf(5)
dcons_gdb="1"
