bytecode locks .bin file after entering homotopy.
Running ireland.mod triggers an exception
Fatal error in bytecode: umfpack_dl_solve failed
in the first iteration so that we enter homotopy mode. This it successful. But subsequently, the mod-file cannot be run a second time due to
model/bytecode/dynamic.bin being locked. It seems that
SaveCode.open(file_name + "/model/bytecode/dynamic.bin", ios::in | ios::binary);
but never closes it in case of an exception.
