0026616: Memory leak in IntTools_Context::Hatcher

Browse Source 
class IntTools_Context
- method:
Geom2dHatch_Hatcher& IntTools_Context::Hatcher
  (const TopoDS_Face& aF)
- method:
IntTools_SurfaceRangeLocalizeData& IntTools_Context::SurfaceData
  (const TopoDS_Face& aF)

The memory allocation is provided using inner allocator of the object.
