It makes me worried that we would call free() on it later. We don't, but that means... > + git_config_get_string("rebase.instructionFormat", &format); ...that this assignment to "format" leaks. So perhaps you'd want to xstrdup the literal, and then make sure the result is freed? Or alternatively use an extra level of indirection (a to_free pointer to store the config value, and then a const pointer for "format"). -Peff
