abort during processing (1.0.20)

error:

terminate called after throwing an instance of 'std::out_of_range'
  what():  vector::_M_range_check: __n (which is 15) >= this->size() (which is 15)

some debug output:

(gdb) p stmt->sql_query_list_id
$1 = 16
(gdb) p  this->ws_query_list.size()
$2 = 15
(gdb) p this->ws_query_list.at(14).c_str()
$3 = 0x7a1530 "SELECT COUNT( * )"

The source is quite big, so what can I provide to ease inspecting this issue?

I will check the code and try (at least and for the moment) to make it terminate "gently" in case there is a mismatch like the one you mentioned above. A minimal test case would of course be appreciated, but I'l keep investigating as soon as I have some more time.

Thanks

Rechecked: same error with 1.0.20b, but "obviously" a different stack trace

and also rechecked: no error with 1.0.19.
