10.17.2 Bugs Fixed

• Compiler bug affecting very large clauses if profiledcode.
• Calling restore/1 when library(clpfd) had been loaded would sometimes crash SICStus with a memory access error.
• library(comclient) did not dispose of all references to COM objects. comclient_garbage_collect/0 did not work correctly (but should not be needed if you use comclient_release/1).
• SP_garbage_collect_external_objects() would reclaim live objects. This affected comclient_garbage_collect/0.
• The Java flag -Dsicstus.path should no longer be needed when using Jasper, except in exceptional circumstances. SICStus will use the location of the SICStus run-time library, e.g. libsprt312.so to set this up automatically.
• SP_initialize() will now return an error code if memory could not be allocated. It used to terminate the process. Among other things this ensures that creating a se.sics.jasper.SICStus object will throw an exception instead of terminating Java if there is insufficient memory.
• library(timeout) is now more precise, in particular when calls to time_out/3 are nested. The resolution has not been improved, it is still on the order of a few tens of milliseconds.
• library(timeout) under Windows could sometimes deadlock or otherwise behave erratically.
• format/[2,3] reported errors inconsistently.
• undo/1: missing meta-predicate declaration.
• library(clpfd): constraints without arguments handled incorrectly; inconsistent overflow handling; heap overflow detection; bugs in element(X,L,Y) with non-ground L; bugs in disjoint2/2 with margin/4 option.
• library(chr): spurious error messages could occur when loading CHR files from all-in-one executables.
• library(objects): Dangling pointer problems with instances if the class was asserted to after the instance had been created.
• library(jasper): Memory leak when calling a Java method. Segmentation fault on Solaris when passing arguments declared as +term.
• library(gauge): The help button did not work under Windows if SICStus was installed in the default location or other folder with a space in the path.
• Foreign resources generated with splfr --exclusive-access could not be loaded more than once into the same process. The only SICStus library affected is library(system).
• Problems with loading and unloading foreign resources if the name was not unique or if file path facts had changed.
• unload_foreign_resource/1 now takes the name of a foreign resource. For backward compatibility it still accepts a file name treated as for load_foreign_resource/1. See Foreign Resources. unload_foreign_resource/1 is still a meta-predicate but the module is ignored.
• SPARC native code issues: flushing the instruction cache, redefining imported predicates.
• The spdet and spxref tools now work also when installed as part of a pre-built binary installation.
• The debugger command `t' (backtrace n) showed too much.
• SP_read_from_string() would leak memory.
• SICStus runtimes will work correctly for executables located at the root of a drive, e.g. as D:\foo.exe.
