Detailed Description

template<class T>
class Dune::DebugAllocator< T >

Allocators implementation which performs different kind of memory checks.

We check:

  • access past the end
  • only free memory which was allocated with this allocator
  • list allocated memory chunks still in use upon destruction of the allocator

When defining DEBUG_ALLOCATOR_KEEP to 1, we also check

  • double free
  • access after free

When defining DEBUG_NEW_DELETE >= 1, we

  • overload new/delte
  • use the Debug memory management for new/delete
  • DEBUG_NEW_DELETE > 2 gives extensive debug output
