VS 2022 passing std::vector from c++/cli to c++ does not work in debug mode

Do you mean passing arguments to another DLL? Show some details to reproduce the problem (or even a sample project).

Are you perhaps mixing Debug and Release versions of your components - which will be a problem if they rely on passing heap allocated items between them.

c++/cli code:

reg_impl = new CGS_PCL_reg() //

int nrPoints=source->GetLength(0);

std::vectorstd::vector<double> src;

std::vectorstd::vector<double> tgt;

for (int i = 0; i < nrPoints; i++)

{

    std::vector<double> s;

	s.push_back(System::Convert::ToDouble(source[i,0]));

	s.push_back(System::Convert::ToDouble(source[i,1]));

	s.push_back(System::Convert::ToDouble(source[i,2]));

    src.push_back(s);

    std::vector<double> t;

	t.push_back(System::Convert::ToDouble(target[i,0]));

	t.push_back(System::Convert::ToDouble(target[i,1]));

	t.push_back(System::Convert::ToDouble(target[i,2]));

    tgt.push_back(t);

}

std::vectorstd::vector<double> value = reg_impl->transformEstimationSVD(src, tgt);

c++ code HEADER:

class GS_PCL_REG_API CGS_PCL_reg : public gspcl_io_base

{

public:

CGS_PCL_reg(void);

virtual ~CGS_PCL_reg(void);  // Destructor
