Getting standard error into Eclipse console? [message #235344]

Hello,

I'm just starting up C again for school and giving Eclipse a whirl this
time. Got Eclipse installed under Ubuntu 9.04 and the ANSI C "hello
world" program working great, but if I try any code that throws errors
(seg fault, floating point errors, etc), the errors don't show up in the
Eclipse console, but the other output does. So I'm curious about 2 things:

1) How to get Eclipse to show standard error (I assume this is the prob?)
...or....
2) How to launch the external command line version of my C++ program when
I click the "play" button in Eclipse. (I don't wanna have to alt-tab and
navigate through bash manually, I'm lazy)

Thanks!!
Seth

I really need this thing to be clarified or probably I will not longer be able to use Eclipse for C developing...

For example, this code makes segmentation fault error. If you run it from Eclipse (use C99 flag), you will not have segmentation fault errors. If you try from the Linux console, you will have the segmentation fault error message.
How is it possible?

int main()
{
	int *array;
	array = calloc(10,sizeof(int));
	for(int i = 1; i < 10; i++)
	{
		array[i] = i;
	}
	sprintf("%d\n", array[1]);

	return 0;
}

The program fails under Eclipse as well, but the exception is not displayed. If you switch to the Debugging perspective, you will see that the program terminated with an exit code of -1. The -1 exit code isn't shown in the console termination message which would have helped you realize this occurred. If you simply debug the program under the debugger you will see the exception displayed by gdb. I have opened: https://bugs.eclipse.org/bugs/show_bug.cgi?id=363383 if you wish to track.
