Ok, so the instrumentation apparently worked and as you got gmon.out
file which to process, the gmon init & exit i.e. opening & saving of
the data works, at least to some extent.

I guess next suspects would be what the C-library mcount() etc functions
do, is the collected data saved correctly and whether gprof actually can 
read the data correctly...


Maybe you could check whether gcov works any better?
I.e. Are both of gprof & gcov broken or only one of them...

PS.  I just tested gprof quickly on Linux and on short run going through
the program mainloop and exiting on user input, it didn't produce any data. 
I had to use the program a bit more to get any data.
