Re: [Boost-users] [Spirit] Semantic actions (binary parser) - user error or bug?

Semantic actions in Karma are supposed to _supply_ the attribute value to generate output from. Therefore your start rule needs to be written as:

start = big_dword >> big_dword[_1 = ref(temp)];

I believe it was the Qi part (use %= instead): start %= big_dword >> big_dword [ref(temp) = _1]; Then the 2nd assertion fails at runtime, however: start %= big_dword >> big_dword; works fine...really strange to me... how can the action affect the attribute?
