but it seems there were still a couple left. These are now gone as well. There seem to be no issues with the ones that were left, but it is just too easy to get it wrong. Declaring buf in function now. This should be faster anyway, since it is located on nearby memory (stack). Inspired by previous find from westor (c708a99955c034e842f913479cc597d87b311394).
