I've just released sbcl-1.1.1. A couple of things to note: firstly
there have been some reports of heap corruption under some circumstances
on the windows build, which is now newly threaded by default; users of
SBCL on windows might wish to be as circumspect as they usually are when
dealing with new releases. Windows users might wish to note the plan to
drop support for unthreaded builds from the next release, and use this
release cycle to make sure that any potential problems are discovered in
advance of the next release.
Secondly, I meant to build the x86-64/Linux binary in a chroot but
forgot, meaning that the binary links to a relatively new libc version
rather than an older one; if this is a problem for anyone, a rebuild
starting from the x86-64/Linux binary for sbcl-1.1.0 should be
changes in sbcl-1.1.1 relative to sbcl-1.1.0:
* enhancement: WITH-COMPILATION-UNIT no longer grabs the world-lock.
(COMPILE and COMPILE-FILE still do.)
* optimization: the SPARC backend now supports the precise generational
(GENCGC) garbage collection. Enabled by default on Solaris/SPARC and
Linux/SPARC. Thanks to Raymond Toy (via CMUCL).
* enhancement: add experimental support for the SB-THREAD feature and the
timer facility on Windows. Thanks to Dmitry Kalyanov and Anton Kovalenko.
Threads are enabled by default, and this version of SBCL is considered
to be the last and final release to officially support building with
* optimization: The compiler no longer rotates loops in some cases where
this transformation actually lead to worse code being generated.
* bug fix: SB-CLTL2:MACROEXPAND-ALL correctly handles shadowing of
symbol-macros by lexical bindings.
* bug fix: stack allocation was prevented by high DEBUG declaration in
* bug fix: SB-EXT:GC-LOGFILE signaled an error when no logfile was set.
(thanks to SANO Masatoshi)
* bug fix: PARSE-NATIVE-NAMESTRING performed non-native parsing when
:JUNK-ALLOWED was true.
* bug fix: type derivation inferred overly conservative types for
unions of array types. (lp#1050768)
