I have the following code: typedef std::vector children_t; children_t children = group.children_.value(); ⋮ children.push_back(*n); bool succeeded = false; BOOST_SCOPE_EXIT((&succeeded)(&children)) { if (!succeeded) { children.pop_back(); } } BOOST_SCOPE_EXIT_END This is yielding compiler errors like this: 193: error: ‘boost_se_params_t_193::boost_se_param_t_0_193’ is not a type 193: error: ‘boost_se_params_t_193::boost_se_param_t_1_193’ is not a type The block of code emitted by the preprocessor starts like this: typedef void (*boost_se_tag_0_193)(int &succeeded); typedef void (*boost_se_tag_1_193)(int &children); … which leads me to conclude that, for some reason, BOOST_SCOPE_EXIT isn't picking up the correct types for its arguments. Has anyone seen this sort of thing before? Is there something I can do to play more nicely with BOOST_SCOPE_EXIT? -- Braden McDaniel
