As I recall, GCC creates duplicates.

Thanks for the reply. I also found your message,
This bug has been fixed,see:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39563
You bug report is related to global variables.
My problem is related to a auto variables. Especially the variable will
be returned.
Something like:
T foo()
{
T a;
T b;
T c;
...
return b;
}
then, the unreturned variable "a" and "c" works well.
But the returned variable "b" will have two debug information entries.
