 The erts-7.3.1 application can be applied independently of other
 applications on a full OTP 18 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-13418    Application(s): erts

               process_info(Pid, last_calls) did not work for Pid /=
               self().


  OTP-13419    Application(s): erts

               Make sure to create a crash dump when running out of
               memory. This was accidentally removed in the erts-7.3
               release.


  OTP-13420    Application(s): erts

               Schedulers could be woken by a premature timeout on
               Linux. This premature wakeup was however harmless.


  OTP-13424    Application(s): erts
               Related Id(s): OTP-10336

               A process communicating with a port via one of the
               erlang:port_* BIFs could potentially end up in an
               inconsistent state if the port terminated during the
               communication. When this occurred the process could
               later block in a receive even though it had messages
               matching in its message queue.

               This bug was introduced in erts version 5.10 (OTP
               R16A).


  OTP-13446    Application(s): erts

               The reference count of a process structure could under
               rare circumstances be erroneously managed. When this
               happened invalid memory accesses occurred.


  OTP-13452    Application(s): erts

               Fix race between process_flag(trap_exit,true) and a
               received exit signal.

               A process could terminate due to exit signal even
               though process_flag(trap_exit,true) had returned. A
               very specific timing between call to process_flag/2 and
               exit signal from another scheduler was required for
               this to happen.

 applications on a full OTP 18 installation.

  OTP-13417    Application(s): inets

               Mend ipv6_host_with_brackets option in httpc

 The mnesia-4.13.4 application can be applied independently of other
 applications on a full OTP 18 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-13423    Application(s): mnesia

               Mnesia transactions could hang while waiting on a
               response from a node who had stopped.
