Thanks for the suggestion Johan, but unfortunately that doesn't work either. The error remains the same when int is replaced by ptrdiff_t instead. I noticed a different error if I explicitly refer to std::random_shuffle (as opposed to just random_shuffle). The "new" errors (when using std::random_shuffle, and int instead of ptrdiff_t) are: (apologies for the extensive error listing) stl_sort.cpp:47: error: invalid initialization of non-const reference of type 'boost::_bi::bind_t<int, boost::_mfi::mf1<int, Foo, int>, boost::_bi::list2<boost::_bi::value<Foo*>, boost::arg<1> > >&' from a temporary of type 'boost::_bi::bind_t<int, boost::_mfi::mf1<int, Foo, int>, boost::_bi::list2<boost::_bi::value<Foo*>, boost::arg<1> > >' /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/bits/stl_algo.h:1766: error: in passing argument 3 of `void std::random_shuffle(_RandomAccessIterator, _RandomAccessIterator, _RandomNumberGenerator&) [with _RandomAccessIterator = __gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >, _RandomNumberGenerator = boost::_bi::bind_t<int, boost::_mfi::mf1<int, Foo, int>, boost::_bi::list2<boost::_bi::value<Foo*>, boost::arg<1> > >]' /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/bits/stl_algo.h: In function `void std::random_shuffle(_RandomAccessIterator, _RandomAccessIterator, _RandomNumberGenerator&) [with _RandomAccessIterator = __gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> >

Any ideas anyone? Thanks again for your help. Kind regards, Nelis Franken
The problem may be that int and ptrdiff_t are distinct types on your platform.
Try the following:
ptrdiff_t customRand(ptrdiff_t n) { return (rand() % n); }
