import IGES file exception

I try to import an IGES file using open cascade and get an exception

The code:
​
IGESControl_Reader reader;
IFSelect_ReturnStatus stat = reader.ReadFile("filePath");
Standard_Boolean ok = reader.TransferRoots();
TopoDS_Shape shape = reader.OneShape();​

I get stat = IFSelect_RetDone in the reader.ReadFile("filePath") line
I get an exception in the reader.TransferRoots() line

IGES file attached
