14.32.1 Bugs Fixed

• The legacy predicates system3:popen/3, system3:shell/[1,2] and system3:system/[1,2] left choicepoints behind.
• Compilation was sometimes very slow when compiling code with constant expressions that would evaluate to very large integers, e.g. p(X) :- X is 7^7^7..
• Prolog text with very large integer constants, e.g. with thousands of digits, was very slow to read.

  Hexadecimal constants no longer suffer from this problem, which provides a solution for data files and other cases when large integer constants need to be read. Large integer constants in other bases, e.g. decimal constants, are still very slow to read.

• The hook predicate Module:attribute_goal/2 no longer catches exceptions locally, which was never intended.
• CLPFD:
  • - element(?X,+List,?Y) now maintains domain consistency in Y if List is given as a list of integers. Pre-4.7.1 behavior was bounds consistency, for no convincing reason.
  • - Binary table/2 could lose domain consistency due to flawed strength reduction.
  • - Prevent recursive propagation during the propagation phase.
  • - Fix GC hazards.
• MiniZinc:
  • - Ignore unrecognized search annotations, with a warning.
• On Windows, subprocesses created with process:process_create/3 would sometimes use a new console window when reading or writing, instead of the streams specified in the call to process:process_create/3. Sometimes the problem happened when the subprocess started a subprocess of its own.
