Hi, all. After the conversation on GDB IRC with GDB developer Jan Kratochvil, a
simple test code supplied by Jan in his bug report on
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58123#c0 can easily demonstrate
this issue in either GCC 4.8.2 or GCC 4.8.1.
class C {
public:
  C() {}
  ~C() {}
  int m() { return 0; }
};
/*  7 */ int main() {
/*  8 */   C a;
/*  9 */   C b;
/* 10 */   C c;
/* 11 */   return a.m() + b.m() + c.m();
/* 12 */ }

You will run "next" command back to line 10, and line 9 until go to the end of
the function main().

Note: the bug #58123 is another issue, Jan expected that the caret should go
back to line 8, but it is not.
