[Sbcl-announce] sbcl-1.1.6 released

[Christophe Rhodes]

Dear all,

I've just released sbcl-1.1.6. There have been reports about some
concurrency tests failing on windows, and some garbage collection
troubles on PowerPC/Linux with the generational garbage collector: users
of those particular systems may wish to exercise extra care in
upgrading, though it's not clear that either of these issues is a
regression.

Changes from sbcl-1.1.5 are appended to this message.

Best wishes,

Christophe

changes in sbcl-1.1.6 relative to sbcl-1.1.5:
* enhancement: the continuable error when defknown-ing over extant
fndb entries can be ignored by passing :overwrite-fndb-silently t
as a keyword argument to sb-c:defknown (after attributes). Useful
to allow defknown to be re-loaded. Use with :allow-other-keys t
for backward compatibility.
* optimization: compiler is much faster in compiling SVREF and (SETF SVREF)
forms.
* bug fix: Prevent a make-array transform from modifying source forms
causing problems for inlined code. Thanks to Bart Botta.
(regression since 1.0.42.11-bis)
* bug fix: clear-output calls the correct gray stream routine,
sb-gray:stream-clear-output. (lp#1153257)
* bug fix: an error is signalled for an invalid format modifier: ~<~@>.
(lp#1153148)
* bug fix: Better error messages for package operations (lp#1154776)
* bug fix: delete-package on a nonexistent package should signal a cerror.
(regression since 1.0.37.44).
* bug fix: accessing &MORE (stack allocated &REST) arguments checks bounds.
(lp#1154946, lp#1072112)
* bug fix: compiling make-array no longer signals an error when the
element-type is an uknown type, a warning is issued instead.
Thanks to James Kalenius (lp#1156095)
* bug fix: SEARCH on generic (non-VECTOR non-LIST) sequence types no longer
produces wrong results for some inputs. (Thanks to Jan Moringen.)
(lp#1153312)

One thing which is definitely a regression, though not sufficiently
clearly revealed by testing during the freeze period, is that sbcl-1.1.6
cannot compile SVREF and (SETF SVREF) of symbol macros. This
unfortunate bug can make it less than suitable some uses, and affects a
number of libraries in quicklisp among other things.

Best wishes,

Christophe
