If anyone has any objections, please let me know. ------------------ From: Ben Hutchings commit 5a1e99dd2028e00998d42029be86835d8ef4a46e upstream. The comparison between traced and symbol addresses is backwards: if the traced address doesn't exactly match a symbol (which we don't expect it to), we'll show the next symbol and the offset to it, whereas we should show the previous symbol and the offset from it.
