[Sbcl-announce] sbcl-1.0.17 has been released

[Christophe R. <cs...@ca...>]

Source is available in SourceForge CVS and on the SourceForge File
Releases page.

Under some conditions (as yet slightly uncertain; see sbcl-devel), the
a stress-test of times in SBCL's regression test suite can cause SBCL
to deadlock.  It is currently believed that this is not in fact a
regression, but it is possible that some rearrangement of code has
caused this failure mode to become more likely: if your code depends
on timers, proceed with care (and please report any failures you
observe to sbcl-devel, to help the diagnosis and cure).

Best,

Christophe

from the NEWS file in the distribution:

changes in sbcl-1.0.17 relative to 1.0.16:
  * temporary regression: user code can no longer allocate closure
    variable storage on stack, due to bug 419 without explicitly
    requesting it. Please consult sbcl-devel for advice if you need to
    use this feature in the meanwhile.
  * new feature: runtime argument --control-stack-size can be used to
    adjust thread default control stack size.
  * enhancement: improved TIME output
    ** all times are reported using the measured accuracy (milliseconds
       for real and GC times, microseconds for everything else.)
    ** processor cycle counts on x86 and x86-64.
    ** interpreted forms are counted for both evaluator modes.
    ** number of lambdas converted by the compiler is reported.
    ** CPU percentage report (computed from real and total run time.)
    ** more comprehensive run time reporting, using a condenced format
    ** interperted form, lambda, and page fault counts are omitted
       when zero.
  * optimization: ADJOIN and PUSHNEW are upto ~70% faster in normal
    SPEED policies.
  * optimization: APPEND is upto ~10% faster in normal SPEED policies.
  * optimization: two argument forms of LAST are upto ~10% faster
    in normal SPEED policies.
  * optimization: NCONC no longer needs to heap cons its &REST list
    in normal SPEED policies.
  * bug fix: SB-FLUID build feature no longer breaks the build. (thanks
    to Sidney Markowitz)
  * bug fix: UNION and NUNION work with :TEST-NOT once more,
    regression since 1.0.9.1. (thanks to Eric Marsden)
  * bug fix: result of MAKE-ARRAY can be stack allocated - regression
    since 1.0.15.36. (thanks to Paul Khuong)
  * bug fix: LAST when always returned the whole list when given a bignum
    as the second argument.
  * bug fix: dynamic extent allocation of nested lists and vectors
    could leak to otherwise accessible parts.
  * bug fix: invalid optimization of heap-allocated alien variable
    reference.
  * bug fix: fasl header checking is less vulnerable to different
    platform word lengths.
  * bug fix: more correct assembler syntax for GNU binutils
    2.18.50.0.4 support.  (thanks to Marijn Schouten)
  * bug fix: fix ECASE warnings from CMUCL-as-xc-host.  (reported by
    Andreas Franke)
  * bug fix: the fopcompiler can handle LOCALLY forms (with no
    declarations) successfully.  (reported by Attila Lendvai)
