Details:

The following code:

#include <octave/oct.h>
#include <octave/load-save.h>
#include <octave/oct-map.h>
#include <octave/ls-hdf5.h>

using namespace std;

typedef symbol_table::symbol_record OctaveSymbolRecord;

int main() {
    auto my_map = octave_map();
    my_map.setfield(string("mykey"),octave_value(0));
    hdf5_ofstream ofs("octave_bug.hdf5");
    write_header(ofs, LS_HDF5);
    do_save(ofs, OctaveSymbolRecord(0, "my_map", octave_value(my_map)),
LS_HDF5, false); 
    return 0;
}

Fails with the following error message:

error: full: invalid operation for %s type: wrong type argument 'scalar
struct'
error: octave_base_value::save_binary(): wrong type argument '<unknown type>'
error: save: error while writing 'my_map' to hdf5 file
