Dear all,
Might be a trivial questions to you guys. I get a scalar problem using hp

std::vector<std::string>solution_names;

solution_names.push_back ("phi");
std::vector<DataComponentInterpretation::DataComponentInterpretation>
data_component_interpretation(1,
DataComponentInterpretation::component_is_scalar);
DataOut<dim,hp::DoFHandler<dim> > data_out;
data_out.attach_dof_handler (dof_handler);
data_out.add_data_vector (scalar_flux,
solution_names,

data_out.build_patches ();
std::string name = "solution.vtk";
std::ofstream output (names.c_str());
data_out.write_vtk (output);
std::cout << "see see 3" << std::endl;
I got the following error:
CDLS-DSA(49490,0x70000c0cb000) malloc: *** error for object 0x7f7f87707c98:
incorrect checksum for freed object - object was probably modified after being

Weixiong,
Can you run this in a debugger, set the breakpoint at the function suggested
here, and see if you can get a backtrace? Alternatively, can you create a
small, self-contained testcase that shows the problem?
Best
W.
