13.16.2 Bugs Fixed

• Interrupt latency problem fixed.
• Fixed exception handling bug introduced in 4.1.3.
• Misencoded and null strings from C are handled gracefully.
• write_term(X,[max_depth(D)]) did not always respect the depth limit.
• seeing/1 and telling/1 now return user for the current input resp. output stream, which was always intended.
• If the standard input stream encounters an invalid character, it will be silently replaced with the Unicode replacement character 0xFFFD. This was already the case for the standard output streams.

  The same behavior, for the standard input and output streams, is now also in effect when running SICStus in the SPIDER IDE.

• When open/[3,4] cannot expand a system property, e.g. open('$FOO/bar.txt', read, S) when the system property FOO is undefined or empty, an exception is raised. Previosly, open/[3,4] silently failed in this case.
• The system property SP_ALLOW_CHDIR could not be set using the environment variable of the same name.
• The spld tool would ignore the --namebase argument for some generated files.
• CLPFD:
  • Dangling pointer hazard fixed for domain variables with frozen goals.
  • Missing propagation problems fixed.
  • sorting/3 could fall into infinite loop.
  • Indexical compilation problems fixed.
• CLPQ/CLPR: called the undefined predicate 'C'/3.
• library(terms): bugs in sub_term/2, term_variables/2, subsumeschk/2 and friends.

• Improvements in how library('linda/server') and library('linda/client') handle server shutdown.

  The server will stop listening for new connections as soon as it receives a shutdown request from a client. Among other things this makes the socket port available for re-use on the same machine.

  A call to linda_client:shutdown_server/0, in the client, will not return until the server has acknowledged the command. This removes a race condition when the client attempts to re-connect to the server.

• A number of problems in library(odbc) has been fixed. There are also some new features and other changes; see above.
