+ A process communicating with a port via one of the
+ <c>erlang:port_*</c> 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 <c>receive</c> even though it had messages
+ matching in its message queue.</p>
+ <p>
+ This bug was introduced in erts version 5.10 (OTP R16A).</p>

+ Calls to <c>erl_drv_send_term()</c> or
+ <c>erl_drv_output_term()</c> from a non-scheduler thread
+ while the corresponding port was invalid caused the
+ emulator to enter an inconsistent state which eventually
+ caused an emulator crash.</p>

+ <p>Driver and NIF operations accessing processes or ports

+ Fix bug in <c>binary_to_term</c> for binaries created by
+ <c>term_to_binary </c> with option <c>compressed</c>. The
+ bug can cause <c>badarg</c> exception for a valid binary
+ when Erlang VM is linked against a <c>zlib</c> library of
+ version 1.2.9 or newer. Bug exists since OTP 17.0.</p>

+ Fixed bug in operator <c>bxor</c> causing erroneuos
+ result when one operand is a big <em>negative</em>
+ integer with the lowest <c>N*W</c> bits as zero and the
+ other operand not larger than <c>N*W</c> bits. <c>N</c>
+ is an integer of 1 or larger and <c>W</c> is 32 or 64

+ Fixed bug in <c>binary_to_term</c> and
+ <c>binary_to_atom</c> that could cause VM crash.
+ Typically happens when the last character of an UTF8
+ string is in the range 128 to 255, but truncated to only
+ one byte. Bug exists in <c>binary_to_term</c> since ERTS
+ version 5.10.2 (OTP_R16B01) and <c>binary_to_atom</c>
+ since ERTS version 9.0 (OTP-20.0).</p>

+ When calling <c>garbage_collect/[1,2]</c> or

+ higher priority than the priority of the process operated

+ This bug has now been fixed.</p>
