When either '-pg' or '-finstrument-functions' is used, the compiler inserts the appropriate profiling hooks. This happens prior to inlining, so the hooks remain in place. Normally this is fine, but with C++ and the heavy use of inline functions and templates, there can be a vast number of trivial functions that are normally optimised away; but with the instrumentation hooks
