Show "(null)" in error message when passed filname to dlopen() was NULL and error occurred It does not make sense to pass file variable (which is NULL) to function save_err_ptr_str() which converts its argument to string. We can call directly save_err_str() with string value. Also it is highly unexpected that GetModuleHandle(NULL) call fails.
