Bug#27015 s_query.q_append() called without s_query.reserve()? 

there is a way to miss allocation for the punctuation marks,
namely if (q == EOF) is true inside of append_identifier(), i.e in case names are not quoted
(not by default).

Replacing q_append with the method with reallocation if needed.

  changing the method that uses reallocation if necessary
