               Related Id(s): ERL-1246

               In rare circumstances, a guard using 'not' could
               evaluate to the wrong boolean value.


  OTP-16657    Application(s): compiler
               Related Id(s): ERL-1253

               A guard expression that referenced a variable bound to
               a boolean expression could evaluate to the wrong value.

 --- erts-11.0.1 -----------------------------------------------------
 ---------------------------------------------------------------------

 The erts-11.0.1 application can be applied independently of other
 applications on a full OTP 23 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-16639    Application(s): erts
               Related Id(s): ERL-1236

               The functionality utilized by BIFs for temporary
               disabling of garbage collection while yielding could
               cause system task queues to become inconsistent on a
               process executing such a BIF. Process system tasks are
               for example utilized when purging code, garbage
               collecting literal data, and when issuing an ordinary
               garbage collection from another process.

               The bug does not trigger frequently. Multiple code
               purges in direct sequence makes it more likely that
               this bug is triggered. In the cases observed, this has
               resulted in a hanging code purge operation.


  OTP-16654    Application(s): erts
               Related Id(s): ERL-1242

               SCTP and UDP recv/2,3 hangs indefinitely if socket is
               closed while recv is called (socket in passive mode).
