+ <section><title>Fixed Bugs and Malfunctions</title>
+ <list>
+ <item>
+ <p>
+ The '-path' flag to 'erl' has been documented. This flag
+ replaces the path specified in the boot script. It has
+ always existed, but was earlier only documented in SASL
+ (script).</p>
+ <p>
+ Own Id: OTP-13060</p>
+ </item>
+ <item>
+ <p>
+ The <c>call_time</c> tracing functionality internally
+ used a time based on OS system time in order to measure
+ call time which could cause erroneous results if OS
+ system time was changed during tracing.</p>
+ <p>
+ This functionality now use Erlang monotonic time in order
+ to measure time. Besides fixing the erroneous results due
+ to OS system time being used, the results are often also
+ better since Erlang monotonic time often has better
+ accuracy and precision.</p>
+ <p>
+ Own Id: OTP-13216</p>
+ </item>
+ <item>
+ <p>
+ Fix behaviour of -delay_write command line switch of
+ epmd, which is used for debugging - in some cases epmd
+ was sleeping twice the requested amount of time.</p>
+ <p>
+ Own Id: OTP-13220</p>
+ </item>
+ <item>
+ <p>
+ Fix race between timeout and exit signal that could cause
+ a process to ignore the exit signal and continue
+ execution. Bug exist since OTP 18.0.</p>
+ <p>
+ Own Id: OTP-13245</p>
+ </item>
+ <item>
+ <p>
+ Fix bug in <c>erlang:halt/1,2</c> for large exit status
+ values, causing either <c>badarg</c> (on 32-bit) or exit
+ with a crash dump and/or core dump (on 64-bit). Make
+ <c>erlang:halt/1,2</c> tolerate any non negative integer
+ as exit status and truncate high order bits if the OS
+ does not support it.</p>

+ was not <seealso
+ marker="erts:time_correction#Time_Warp_Safe_Code">time
+ warp safe</seealso>. This since it used the same time as
+ returned by <seealso
+ marker="erts:erlang#now/0"><c>erlang:now/0</c></seealso>
+ when calculating timeout. This has now been fixed.</p>
+ <p>
+ Own Id: OTP-13254 Aux Id: OTP-11997, OTP-13222 </p>

+ <p>
+ Own Id: OTP-13282 Aux Id: ERL-79 </p>
+ </item>
+ <item>
+ <p>
+ Out of memory errors have been changed to cause an exit
+ instead of abort.</p>
+ <p>
+ Own Id: OTP-13292</p>
+ </item>
+ <item>
+ <p>
+ When calling <c>garbage_collect/[1,2]</c> or
+ <c>check_process_code/[2,3]</c> from a process with a
+ higher priority than the priority of the process operated
+ on, the run queues could end up in an inconsistent state.
+ This bug has now been fixed.</p>

+ Own Id: OTP-13298 Aux Id: OTP-11388 </p>
+ </item>
+ <item>
+ <p>
+ A workaround for an issue with older gcc versions (less
+ than 5) and inline assembly on 32-bit x86 caused an
+ emulator crash when it had been compiled with a newer gcc
+ version. An improved <c>configure</c> test, run when
+ building OTP, now detects whether the workaround should
+ be used or not.</p>

+ <p>Introduced new statistics functionality in order to
+ more efficiently retrieve information about run able and

+ Time warp safety improvements.</p>
+ <p>
+ Introduced the options <c>monotonic_timestamp</c>, and
+ <c>strict_monotonic_timestamp</c> to the trace,
+ sequential trace, and system profile functionality. This
+ since the already existing <c>timestamp</c> option is not
+ time warp safe.</p>
+ <p>
+ Introduced the option <c>safe_fixed_monotonic_time</c> to
+ <c>ets:info/2</c> and <c>dets:info/2</c>. This since the
+ already existing <c>safe_fixed</c> option is not time
+ warp safe.</p>

+ Own Id: OTP-13222 Aux Id: OTP-11997 </p>

+ Fix a register race where down nodes goes undetected in
+ epmd</p>
+ <p>
+ Own Id: OTP-13301</p>
+ </item>
+ <item>
+ <p>
+ Improved the gcc inline assembly implementing double word
+ atomic compare and exchange on x86/x86_64 so that it also
+ can be used when compiling with clang.</p>
+ <p>
+ Own Id: OTP-13336</p>
+ </item>
+ <item>
+ <p>
+ An optimization preventing a long wait for a scheduler
+ thread looking up information about a process executing
+ on another scheduler thread had unintentionally been lost
+ in erts-5.10 (OTP R16A). This optimization has now been
+ reintroduced.</p>
