Details:

Hi,

The following code fails at runtime:
#include <fstream>
#include <string>
#include <octave/oct.h>
#include <octave/octave.h>
#include <octave/toplev.h>
#include <octave/load-save.h>
#include <octave/parse.h>

using namespace std;

typedef symbol_table::symbol_record OctaveSymbolRecord;
 
int main (int argc, char** argv)
{

    auto A = ComplexNDArray(dim_vector(10,20));
    OctaveSymbolRecord a_record = OctaveSymbolRecord(0, string("A"),
octave_value(A));

    ofstream ofs;
    ofs.open("a.octave_bin",ofstream::out);
    if( !ofs.good() ) {
        cerr << "ERROR: failed to open " << argv[2] << " for writing" <<
endl;
        return 1;
    }
    //load_save_format fmt = load_save_format(LS_BINARY);
    load_save_format fmt = load_save_format(LS_HDF5);
    write_header(ofs, fmt);
    do_save(ofs, a_record, fmt, false); 
    ofs.close();

    return 0;
}

Error message is:
terminate called after throwing an instance of 'std::bad_cast'
  what():  std::bad_cast

My assumption is that problem is with HDF5 format support, as after changing
format to LS_BINARY crash goes away.

Please, advise.

Thanks,
  Dmitry
