Data Exchange - errors occur on Step file import STEPControl_Reader::ReadFile

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
    }

The file is invalid, because some oriented edges contain a non-existent reference to EDGE_CURVE - nothing can be done about this, I suggest closing the bug.

An example of an incorrectly oriented edge: ORIENTED_EDGE ( 'NONE', *, *, #18446744073709551615, .T. )

Dear ika, please check my findings and confirm.

Dear Commenter 1,

I totally agree with ssafarov's problem description.

Please close the issue.

Closed.
