error.c can't use calloc and OCI_FREE

[kornefalk]

The memory allocated

OCI_Error *err = (OCI_Error *) calloc(1, sizeof(*err));

but deleted with

OCI_FREE(err)

Either the allocation must be changed or the free function must be called instead of OCI_FREE since OCI_FREE tries to free the memory pointer - sizeof(*mem_block) instead of the allocated memory using calloc

You're right indeed. Good catch :)

Fix committed !

Thanks for reporting :)
