               Related Id(s): ERIERL-436

               Fixed a performance bug that caused repeated matches of
               large records to take a very long time to compile.

  OTP-16193    Application(s): erts

               A literal area could prematurely be released before all
               uses of it had been removed. This occurred either when
               a terminating process had a complex exit reason
               referring to a literal that concurrently was removed,
               or when a terminating process continued executing a
               dirty NIF accessing a literal (via the heap) that
               concurrently was removed.


  OTP-16224    Application(s): erts
               Related Id(s): ERL-1044

               Fix bug causing VM crash due to memory corruption of
               distribution entry. Probability of crash increases if
               Erlang distribution is frequently disconnected and
               reestablished towards same node names. Bug exists since
               OTP-21.0.


  OTP-16265    Application(s): erts
               Related Id(s): ERL-1064

               Fixed bug causing crash of VM built with configuration
               --enable--sharing-preserving. Provoked when a sent
               message contains both a bit string and the heap binary
               (< 65 bytes) which the bit string was matched from. Bug
               exists since OTP-19.0 but has seen to be easier to
               provoke since OTP-22.1.
