Description

Restoration of attached shape leads writing out of memory:

1640 void BSplCLib::GetPole(const Standard_Integer Index,
...
1651 for (k = 0; k < Dimension; k++) {
1652 Pole(Position) = pole[k];
1653 Position++;
1654 }

This situation caused by "PrepareInsertKnots" function in the same file, where new knot count computed.

Steps to reproduce

restore Attachment 1 (BREP)
