What information does it produce ?
Which version of gcc are you using ?
Which version of gprof are you using ?
Is this a cross compiler or a native compiler ?
For which target was the compiler configured ?

It should do.  There may be a bug somewhere or possibly you need to 
modify the procedure you followed.  If you can provide a full test case 
  we may be able to investigate further.
