Subj : Problems with tellg()

I am not sure if the problem below is a bug or an error on my part, but 
after reading data from a file I check the file cursor position using 
::tellg() and tellp() and I get -1; an error in the stream.
---- snip ----
bool data;
fstream f(blabla, blabla)
std::cout << f.tellg() << std::endl; //<--- returns 0
f >> data;
std::cout << f.tellg() << std::endl; //<--- returns -1
-----

The data stored in 'blabla' is '010101', all bool values.
If I only read the first value in the file (zero) why is tellg() 
reporting a failure in the stream.
A more comprehensive example is at:

Can anyone help?
