12.8.4 Known Issues

The following are known issues with this release of SICStus. See Limitations in the Current Release for more information about missing or incomplete features in this release.

• Exceptions in interpreted code will not get accurate source info in the source linked debugger.
• Saved-states and `.po' files are not portable across architectures that have the same word size, which they should be. This will be fixed in release 4.1.0.
• SICStus Prolog does not verify that Prolog text is in Unicode NFC format.

  When reading terms, SICStus Prolog currently does not verify that the input text contains valid Unicode 5.0 characters in Normal Form C. See Syntax of Tokens as Character Strings.

  This is not a problem as long as the input is in the proper format but it will accept some input that may be rejected or interpreted differently in a future version of SICStus Prolog.
