In using gprof on a large C++ app, there are a number of functions in the output that do not have any class name or parameters associated with them. In a thorough search of the app source, I cannot find any functions defined with a particular name that shows up like this in the gprof output. How can I track down where these functions live? In the call trace section, they show up as "spontaneous," so I can't even tell from where they are called. Any guidance would be most appreciated. Thanks. MR
