sbcl-1.1.12 released

Dear all,

I have just released sbcl-1.1.12 to the world; the release notes are
appended to this message.  Of note in this release cycle: I will no
longer pretend that a fix for the type annotation problem referred to in
the last two release messages is imminent, and a launchpad bug has been
filed at <https://bugs.launchpad.net/sbcl/+bug/1229340>, and progress
can be tracked there.  Also, there have been reports of heap corruption
/ garbage collection failures on the 32-bit x86 platform, probably
dating back a few months; if anyone out there is experiencing this and
has a repeatable test case, we would appreciate details.

Best wishes,

Christophe

changes in sbcl-1.1.12 relative to sbcl-1.1.11:
  * enhancement: Add sb-bsd-sockets:socket-shutdown, for calling
    shutdown(3). (thanks to Jan Moringen, lp#1207483)
  * enhancement: document extensible sequences.  (thanks to Jan Moringen,
    lp#994528)
  * optimization: EQUAL and EQUALP transforms are smarter.
    (thanks to Elias Martenson, lp#1220084)
  * optimization: CHAR-EQUAL is faster for constant and base-char arguments.
  * bug fix: probe-file now can access symlinks to pipes and sockets in
    /proc/pid/fd on Linux. (reported by Eric Schulte)
  * bug fix: SBCL can now be built on Solaris x86-64.
  * bug fix: Floating point exceptions do not persist on Solaris anymore.
  * bug fix: (setf . a) is pprinted correctly (reported by Douglas Katzman).
  * bug fix: handle compiler-error in LOAD when it's not run from inside EVAL.
    (lp#1219601)
  * bug fix: SB-GMP:MPZ-POW no longer segfaults given a non-bignum base.
    (thanks to Stephan Frank)
  * bug fix: space allocation of result bignums in SB-GMP is more accurate.
    (thanks to Stephan Frank, lp#1206191)
  * bug fix: sb-safepoint can now reliably handle signal interruptions of
    foreign code. (lp#1133018)
  * bug fix: the compiler-macro for MAKE-INSTANCE when emitting "fallback"
    constructors no longer fails to merge actual and default initargs
    (thanks to Jan Moringen, lp#1179858)
  * bug fix: the compiler-macro for MAKE-INSTANCE when emitting "fallback"
    constructors handles non-KEYWORD initialization arguments more correctly.
  * bug fix: loading the SB-SIMPLE-STREAMS contributed module no longer
    clobbers FILE-NAMESTRING.  (thanks to Anton Kovalenko, lp#884603)
  * bug fix: class definitions with CPLs inconsistent with their metaclasses
    are less likely to destroy the object system's integrity.  (lp#309076)
  * bug fix: restart clause parsing in RESTART-CASE is more in line with the
    standard.  (lp#1203585, thanks to Jan Moringen)
  * bug fix: silence a note from RESTART-CASE under high-SPEED optimization
    settings.  (lp#1023721)
  * bug fix: getting the order of arguments to
    SB-MOP:SET-FUNCALLABLE-INSTANCE-FUNCTION wrong produces a sensible error
    rather than a failed AVER.  (reported by Paul Nathan)
  * bug fix: Parsing of &optional/&key/&rest arguments now never overwrites
    arguments during copying on x86 and x86-64; it may still happen on other
    platforms when there are more fixed arguments than stack slots.
