I have found a memory leak when freeing a statement handle which has had
parameters bound in psqlodbc-08.00.0101. I was able to eliminate the
leak by adding:
SC_free_params(self, STMT_FREE_PARAMS_ALL);
to line 330 of statement.c in the SC_Destructor method. I'm not
familiar enough with the code to know if this is a sensible fix.

Can you provide an example program that shows the memory leak?

In the attached program, each query iteration leaks 12 bytes per input
variable. Output variables have no effect.
