Summary:                    Crash on failure to execute SQL
Description: 
* crashes when there is a SQL execute error.

I have attached a valgrind stack of the error. It is impossible to
reproduce in gdb because this error causes corrupted memory, which destroys
the stack in gdb.

In any case, the unixODBC code is very difficult to get a heads up on, but
I *think* that you cannot free the stmt if there was an error. I cannot
find any sample code to confirm this though...

Version is actually 1.4.22.1

res_odbc isn't dependent on FreeTDS.
