gdb does not stops inside a template function

Hi.
 I have the following problem with gdb6.3 :
If I put a breakpoint on a line inside a function template,
the gdb not always stops there.

Please see attached ".cpp" file and the gdb session transcript
(file: "templ_dbg.1.output").
It can be seen that gdb stops on first call to "f",
but not on second.

Regards and thank you,
  Dima.

P.S.
 I use various versions of gcc compiler (3.3.6, 4.0.0),
the result was the same.
