free(info.errors) leads to a assertion error on the heap. 

On Windows it reads:

is_block_type_valid(header->_block_use).

Memory for info.errors is allocated in the osdi device dll
during the call to

      descr->setup_instance((void *)&handle, inst, model, temp,
                            connected_terminals, sim_params, &init_info);

(in fcn OSDIsetup(), line 254 of osdisetup.c).
Therefore ngspice is not the owner of this memory and thus cannot free it.

Fixes bug no. 803.
