Hi all, 
GDB 7.5 under Emacs 24.2 on MacOS 10.8 is not working.  
When I involve GDB by M-x gdb, the -i=mi is added by defined. 
The GDB prompt is a very long and strange-looking  string: like 
"time={wallclock=..., user=..., system=..., strat=..., end=...}", 
when I type run on GDB buffer (even for helloworld.c), 
the program is not running. What might be the problem?

Thanks.
