[Bug c++/23296] New: Combination of -finstrument-functions and -O3 produces incorrect results

["bart dot vanassche at yucom dot be" <gcc-bugzilla at gcc dot gnu dot org>]

When compiling code with gcc 4.0.0 or 4.0.1 and when specifying both the
-finstrument-functions and the -O3 options, then __cyg_profile_func_enter() is
called two or more times successively with exactly the same arguments (called
function pointer and call site pointer). This should never happen.
