Hello

in the attachment there is a single c++ file.

on debian squeeze with g++ (Debian 4.4.5-8) 4.4.5 it compiles. debian 
standard libboost1.42-dev is installed. if you run the program:

erik_at_ludwig:~/allesfresser/karma_problem$ ./a.out
ruleSetModal(subCall(projectMemberIdentifier(siemensAltNumber=100, 
fanucNumber=0, name=))
erik_at_ludwig:~/allesfresser/karma_problem$

that's the required behaviour.

now on new system with g++ (Debian 4.7.1-7) 4.7.1, and libboost1.49-dev, 
it does not compile. a short excerpt of the enormously long chain of 
error message:

problem.cpp:254:5:   required from 
‘astGenerate<OutputIterator>::astGenerate() [with OutputIterator = 
std::back_insert_iterator<std::basic_string<char> >]’
problem.cpp:307:56:   required from here
/usr/include/boost/spirit/home/support/attributes.hpp:519:28: error: 
cannot convert ‘const boost::variant<astProjectMemberIdentifier, 
astErikNcBohrPlanSenk>’ to 
‘boost::spirit::traits::attribute_size<boost::optional<boost::variant<astProjectMemberIdentifier, 
astErikNcBohrPlanSenk> >, void>::type {aka unsigned int}’ in return

if you remove the rule in line 254 (ruleSetModal = "ruleSetModal(" << 
-ruleSubCall << ')';), then the program will compile. but it will output 
nothing of course. i need this line. it worked all the times and now 
after update it does not work.

honestly i do not understand the long chain of error message. i checked 
with boost 1_51_1 with the same not working result. also with clang++ 
compiler it does not work with the same error message. maybe someone on 
the list can enlighten me why this does not compile anymore.

Thanks
Erik
