That should be easy, see below.

Hi Hartmut, Thanks for your help. I've upgraded my version of Spirit to the one from Boost 1.44, so things work better now. However, I'm still unable to compile when I change my rule to something like: start = a_rule | *b_rule. The * and + operators cause the compiler to generate the following error: boost/spirit/home/qi/detail/assign_to.hpp:109: error: invalid static_cast from type ‘const std::vector’ to type ‘int'. Any ideas? Thanks, Vitaly
