a) This is the right gcc list for the question, but we are probably
the wrong people to ask.  As far as most of us are concerned 4.0.3 is
ready for production code.  It is being used in the Fedora Core
GNU/Linux distribution, for example.  But only you can decide whether
is ready for your code.

b) gprof is usually covered on the binutils mailing list.  See
       http://sourceware.org/binutils/
   If you want to profile shared objects, you need to compile them
   with profiling turned on.  If you do that, it should work.  Or use
   oprofile, which does not require a special compilation option.
