Recently I installed CEDET from trunk and realized that query-replace
is not working as it should if I'm trying to replace a string which
occurs on a symbol. query-replace works properly as long as the
replaced text is within comments. If it occurs on a symbol, the "query
replacing..." string in the status on the bottom of the screen
disappears and a symbol description appears instead. This disables the
query-replace and pressing "y" enters "y" to the file.
