a problem when running sparc-rtems-gdb hello.exe

[Justin Cui]

hi,
	up to now, I have installed all the develope enviornment on Cygwin1.1 .And I compile the hello_world_c 4.5.0
examples with no errors. I enter the o-optimize directory and sparc-rtems-gdb hello.exe. As the document specifies,
I type the instructions of target sim, load and run. It seems that all are ok now. But the hello.exe seems to be
stuck. I press Ctrl-C and gdb says: 
	Program received signal SIGINT, Interrupt.
	0x2001134 in zerobss () 
What's wrong? 
I try again. Just load, run. This time I don't press ctrl-c but the enter key. Hello.exe wakes up and
displays the following lines:
	*** HELLO WORLD TEST ***
	Hello World
	*** END OF HELLO WORLD TEST ***

	Program exited normally.

I try more. In fact, When hello.exe is running, any key such as a,b,c,... can wake it up and let it run to exit.
Why this happens?

Sincerely,
Justin
