Problem occurs in TransferRoot.

Please refer the following code:
    STEPControl_Reader aReader;
    IFSelect_ReturnStatus status = aReader.ReadFile(this->strStepFileName.c_str());
    if (status != IFSelect_RetDone)
        return nullptr;

    aReader.WS()->TransferReader()->TransientProcess()->SetTraceLevel(2); // increase default trace level

    Standard_Boolean failsonly = Standard_False;
    aReader.PrintCheckLoad(failsonly, IFSelect_ItemsByEntity);

    // Root transfers
    Standard_Integer nbr = aReader.NbRootsForTransfer();
    aReader.PrintCheckTransfer(failsonly, IFSelect_ItemsByEntity);
    for (Standard_Integer n = 1; n <= nbr; n++) {
        Standard_Boolean ok = aReader.TransferRoot(n); // Error Occurs
    }
