There is always:

  #if CONFIG_USE_XMALLOC
  void *xmalloc(size_t size); /* use ours */
  #else
  #define xmalloc malloc /* don't use ours */
  #endif

Unconditionally using your custom malloc everywhere because there is
something wrong with some mallocs is silly. (Is that really
the case in OpenSSL?)
