comeau reports no error, and with stlport5 testcase works fine.
$ g++ -I/usr/include/stlport main.cpp -o main -lstlport && ./main
Hello 1
Hello 2
with libstdc++ i get:
$ g++ main.cpp -o main && ./main

This is a well knows issue with the current standard binders, see, for example:
http://gcc.gnu.org/ml/libstdc++/2000-06/msg00210.html
It is possible to extend the implementation, but the real way to go is moving
to the new generalized bind facility, which will be in C++0x and we are already
providing as part of our tr1 delivery. It would be (modulo tr1 namespace
decorations...):
bind(std::ptr_fun( print ), _1, str)

Actually this is valid C++ via DR 106.

Ah, interesting! Therefore, if I understand correctly DR 106, when the C++
front-end will implement the resolution, this kind of bind2nd usage will
magically start working without changing at all the library... On the other
hand, Bjarne' observation in DR 106 is also interesting, because maintains that
the library is mainly at fault for the binders... and this is already fixed in
tr1::bind! Making progress everywhere!
