 for aliasing bug
From The Jargon File (version 4.4.7, 29 Dec 2003) :

  aliasing bug
   n.
  
      A class of subtle programming errors that can arise in code that does
      dynamic allocation, esp. via malloc(3) or equivalent. If several pointers
      address (are aliases for) a given hunk of storage, it may happen that the
      storage is freed or reallocated (and thus moved) through one alias and then
      referenced through another, which may lead to subtle (and possibly
      intermittent) lossage depending on the state and the allocation history of
      the malloc arena. Avoidable by use of allocation strategies that never
      alias allocated core, or by use of higher-level languages, such as LISP,
      which employ a garbage collector (see GC). Also called a stale pointer
      bug. See also precedence lossage, smash the stack, fandango on core,
      memory leak, memory smash, overrun screw, spam.
  
      Historical note: Though this term is nowadays associated with C
      programming, it was already in use in a very similar sense in the Algol-60
      and FORTRAN communities in the 1960s.

  stale pointer bug
  aliasing bug
  
      (Or "aliasing bug") A class of subtle
     programming errors that can arise in code that does dynamic
     allocation, especially via malloc or equivalent.
  
     If several pointers address (are "aliases for") a given hunk
     of storage, it may happen that the storage is freed or
     reallocated (and thus moved) through one alias and then
     referenced through another, which may lead to subtle (and
     possibly intermittent) lossage depending on the state and the
     allocation history of the malloc arena.  This bug can be
     avoided by never creating aliases for allocated memory, or by
     use of a higher-level language, such as Lisp, which
     employs a garbage collector.
  
     The term "aliasing bug" is nowadays associated with C
     programming, it was already in use in a very similar sense in
     the ALGOL 60 and Fortran communities in the 1960s.
