+ <p>
+ A timer internal bit-field used for storing scheduler id
+ was too small. As a result, VM internal timer data
+ structures could become inconsistent when using 1024
+ schedulers on the system. Note that systems with less
+ than 1024 schedulers are not effected by this bug.</p>
+ <p>
+ This bug was introduced in ERTS version 7.0 (OTP 18.0).</p>

+ Own Id: OTP-14548 Aux Id: OTP-11997, ERL-468 </p>
+ </item>
+ <item>
+ <p>
+ 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>
+ <p>
+ Own Id: OTP-14590 Aux Id: ERL-474 </p>
+ </item>
+ <item>
+ <p>
+ Fix bug causing VM crash when a module with
+ <c>-on_load</c> directive is loaded while
+ <c>erlang:trace(on_load, ...)</c> is enabled.</p>
+ <p>
+ Own Id: OTP-14612</p>

+ Fix performance bug in pre-allocators that could cause
+ them to permanently fall back on normal more expensive
+ memory allocation. Pre-allocators are used for quick
+ allocation of short lived meta data used by messages and
+ other scheduled tasks. Bug exists since OTP_R15B02.</p>

+ <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
