Looks like """ static boost::regex_error std_boost_exception(boost::regex_error(boost::regex_constants::error_bad_pattern)); """ ambiguous parsing is resolved differently by gcc and clang. gcc resolves it as declaration of 'std_boost_exception' variable while clang tries to parse it as complex 'std_boost_exception()' function declaration.
Ended up being a gcc bug to accept invalid code: https://gcc.gnu.org/PR86564 Clang's bug report in case it's more complicated than that: https://bugs.llvm.org/show_bug.cgi?id=47316 dev-util/source-highlight will need a fix.
