You misunderstood the strace output; make_temp_file will create the file so it can be deleted later on. But with -save-temps no file is created. There is some minor cleanup of collect2 that could improve compile time performance (slightly) in that does not need to call make_temp_file until after decided that the collecting of cdtor needs to happen. Anyways as I mentioned the cdtor.c files are NOT used. Yes a temporary file is created (but it is empty) when not using -save-temps. No file is created when you use -save-temps.
