problem with gprof

[Van Alsenoy Kris]

Dear,

Running gprof does not produce the customary list of time spend in the different subroutines. 
The only output I get is the explanations of the of the different entries and only what is show below as list of the time spend in the different routines :

                                       4             past end of text [77]
[77]     0.0    0.00        0.00       0+4      past end of text [77]
                                       4             past end of text [77]

I am running gprof on my Mac, but used gprof already on other Unix machines successfully.
I have gcc.4.7 (still running Lion) and Xcode 4.6.3. installed and compiled my fortran program using gfortran with the -pg flag.

Can you suggest what I need to do to remedy this ?

Thanks in advance,
sincerely,
kris
