Hi Harmut,

Did you uncomment the line:
//#include <boost/spirit/include/qi_no_skip.hpp> ?

It is commented out in the code below. If I include this line, compilation
fails.
You also have to check optimizations because the code below is not using
no_skip[] in the grammar so there is a chance that a smart compiler that is
not in debug mode might ignore the non-used code.
In my case I am in debug mode, no optmizations and including the
qi_no_skip.hpp header suffices to get the error.

Thanks for your attention !
