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).
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
* optimization: ADJOIN and PUSHNEW are upto ~70% faster in normal
* 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 184.108.40.206. (thanks to Eric Marsden)
* bug fix: result of MAKE-ARRAY can be stack allocated - regression
since 220.127.116.11. (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
* bug fix: fasl header checking is less vulnerable to different
platform word lengths.
* bug fix: more correct assembler syntax for GNU binutils
18.104.22.168.4 support. (thanks to Marijn Schouten)
* bug fix: fix ECASE warnings from CMUCL-as-xc-host. (reported by
* bug fix: the fopcompiler can handle LOCALLY forms (with no
declarations) successfully. (reported by Attila Lendvai)
