The following details a non-fatal bug.  It results in a small memory-leak.
Within oci_execute(oci8.c), a
handle is allocated for OCIParam *param.

A call to OCIParamGet() follows in which
param is passed as an out variable.  After the call,
param receives a new handle value.  The original allocated handle was lost.  

The call to OCIHandleAlloc() is unnecessary
and results in unrecoverable memory.  A patch follows that
details the above said.  It has been tested successfully.
