-profile isn't a gcc option.  This might be the problem.  Try -p or -pg. 
  -pg will give more info.

It isn't clear what your problem is.  What profiles are you getting? 
Why do you think they are wrong?

Gcc contains multiple programs.  If you compiled all of them with 
profile info, then the profile output files may be overwriting each 
other.  Use gcc -v to see what all the gcc driver does, and try running 
individual programs instead of running the gcc driver.
