If this is not a multiple query, ensure that it has been

against a wrong (too big) length passed to mysql_real_query(),
mysql_prepare()... which can generate garbage characters at the
end. If the query was initially multiple, found_colon will be false
only when we are in the last query; this last query had already
been end-spaces-stripped by alloc_query() in dispatch_command(); as
end spaces are the only thing we accept at the end of a query, and
they have been stripped already, here we can require that nothing
remains after parsing.
