Re: Assertion `thd' failed for subquery errors
probably a known issue:

19194 void st_select_lex::print(THD *thd, String *str, enum_query_type query_type)
19195 {
19196 /* TODO: thd may not be set for sub queries, but this should be fixed */
19197 DBUG_ASSERT(thd);
19198 if (!thd)
19199 thd= current_thd;
