Debugging static variable in inlined member function

["Peng Yu" <pengyu.ut@gmail.com>]

Hi,

I have the following program listed below this email. I can not print
_a in the inlined version. But it is OK to print _a in the non-inlined
version. Can you tell me how to debug the inlined version of _a?

(gdb) s
main () at main.cc:32
32        std::cout << a.a() << std::endl;
(gdb) s
A::a (this=0xbff21077) at main.cc:11
11            std::cout << "inline" << std::endl;
(gdb) n
inline
12            ++ _a;
(gdb) p _a
No symbol "_a" in current context.

Thanks,
Peng
