throw (std::bad_alloc)

These are replaceable signatures:

• normal single new and delete (no arguments, throw bad_alloc on error)
• normal array new and delete (same)
• nothrow single new and delete (take a nothrow argument, return NULL on error)
• nothrow array new and delete (same)

Placement new and delete signatures (take a memory address argument, does nothing) may not be replaced by a user's program.
