13.10.2 Bugs Fixed

• SP_event() handlers are no longer allowed to run during SP_fclose(), which sometimes needs to perform some cleanup by calling Prolog code. This can no longer cause SP_event() handlers to run.
• Exceptions during exception handling would cause the top-level to exit.
• SP_event() handlers were not always called during event handling. One symptom was that, at least on Windows, timeout:time_out/3 could not always interrupt a goal called from an event handler.
• Bug in redefining multifile predicates.
• sockets:socket_select/7 leaked memory on Windows.
• library(queues): bug in portray_queue/1.
• library(clpfd): Incorrect reification and efficiency bugs in arithmetic relations involving division, mod and rem; incorrect handling of inf and sup in table/[2,3].
