When length of string to replace minus length of string to replace to is bigger than input string and processing mode allows for binary (memcmp or std::string::find()) comparison, REPLACE may trigger invalid capacity assertion and query processing will stop. The fix is to properly count the number of occurences of the string to replace, basically.
