Exception during Meshing / Missing triangles

Hello,

when I import the attached step file and try to mesh it, I receive an exception in one of the faces. I use OCC 6.5.1 but the Exception also occurs in the current beta-Version of OCC 6.5.3.

The exception occurs in the methode BRepMesh_DataStructureOfDelaun::AddElement(const BRepMesh_Triangle& theElement)
in the line
myLinks(ed2).Append(ElemIndex);

If I use a try-catch-block to handle the exception, some triangles are missing in the triangulation

Here is some sample-Code to reproduce this error:

Handle(TDocStd_Document) hDoc;
XCAFApp_Application::GetApplication()->NewDocument("MDTV_XCAF", hDoc);
STEPCAFControl_Reader reader;
reader.SetColorMode(true);
reader.ReadFile(strFileName);
reader.Transfer(hDoc);

for (TDF_ChildIterator it(XCAFDoc_DocumentTool::ShapesLabel(hDoc->Main())); it.More() && !progress.canceled(); it.Next())
{
if (XCAFDoc_ShapeTool::IsSimpleShape(it.Value()))
{
TopoDS_Shape shapeCurrent;
XCAFDoc_ShapeTool::GetShape(it.Value(), shapeCurrent);

TopExp_Explorer expFace;
expFace.Init(shapeCurrent, TopAbs_FACE);
int nMin(371), nMax(371); //The exception occurs in face 371
for (Standard_Integer numFace = 0; expFace.More(); expFace.Next(), ++numFace)
{
if (numFace nMax)
continue;
TopoDS_Face myFace = TopoDS::Face(expFace.Current());
Handle(Poly_Triangulation) myT = BRep_Tool::Triangulation(myFace, myLocation);
if (myT.IsNull())
{
BRepMesh_IncrementalMesh Mesh(myFace, 0.7, Standard_False, 0.75);
myT = BRep_Tool::Triangulation(myFace, myLocation);
}
}
}
}

Regards
