The code shown below works nicely when compiled with -O2 or -O2 -g.
However, it fails when compiled with -g, but only for std::complex<float>. For
the other types it works well. Valgrind gives piles of uninitialized value
errors.
The same results are obtained when building on other Linux platforms. Also hen
using bind1st the same problems arise.
It works well with g++-3.4.3 though.
Cheers,

Summary: std::transform is incorrect with std::multiples and
bind2nd for complex<float>
