Input
=3D=3D=3D=3D=3D
```
template<typename... T> void f(T&&...zzargs) {}
int main() { f(0); }
```

g++-11 -Wall -ggdb3 x.cpp

Observed output
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
=C2=BB gdb a.out
GNU gdb (GDB; openSUSE Tumbleweed) 11.1
...
(gdb) b main
(gdb) r
...
Breakpoint 1, main () at x.cpp:2

No symbol "zzargs" in current context.


Expected output
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

(gdb) info args
zzargs =3D {0}
(gdb) p zzargs
$1 =3D {0}

or something of the sort.
