Research direction

Start by inspecting actions.hpp around cond_phrase_push and the call site in src/phrase_element_grammar.cpp:41. Reproduce the warning with the documentation build, trace the saved_conditional initialization path, and consider the issue done when the build no longer reports this warning.

Written by the indexing model from the issue text.

Description

We get this warning every time we build the docs:

    inlined from ‘void quickbook::quickbook_grammar::impl::init_phrase_elements()’ at /home/alandefreitas/Documents/Code/C++/boost/tools/quickbook/src/phrase_element_grammar.cpp:41:65:
