The problem is that both EVALs sequentially write to the same LVAR.
-305:
- (Reported by Dave Roberts.)
- Local INLINE/NOTINLINE declaration removes local FTYPE declaration:
-
- (defun quux (x)
- (declare (ftype (function () (integer 0 10)) fee)
- (inline fee))
- (1+ (fee)))
-
- uses generic arithmetic with INLINE and fixnum without.

306: "Imprecise unions of array types"
a.(defun foo (x)
(declare (optimize speed)
(used on non-x86 platforms) being a more complete solution then what
is done on x86.
+ On x86/linux large portions of tests/debug.impure.lisp have been commented
+ out as failures. The probable culprit for these problems is in x86-call-context
+ (things work fine on x86/freebsd).
+
More generally, the debugger internals suffer from excessive x86/non-x86
conditionalization and OAOOMization: refactoring the common parts would
be good.
(sparc and x86 at least)
Since SBCL 0.8.20.1 this is hidden unless *SHOW-ENTRY-POINT-DETAILS*
- is true.
+ is true (instead there appear two TEST frames at least on ppc). The
+ underlying cause seems to be that SB-C::TAIL-ANNOTATE will not merge
+ the tail-call for the XEP, since Python has by that time proved that
+ the function can never return; same happens if the function holds an
+ unconditional call to ERROR.
355: change-class of generic-function
(reported by Bruno Haible)
#.SB-EXT:SINGLE/DOUBLE-FLOAT-POSITIVE-INFINITY. These tests have been
disabled on Darwin for now.
-373: profiling issues on ppc/darwin
- The following bit from smoke.impure.lisp fails on ppc/darwin:
- (progn
- (defun profiled-fun ()
- (random 1d0))
- (profile profiled-fun)
- (loop repeat 100000 do (profiled-fun))
- (report))
- dropping into the debugger with a TYPE-ERROR:
- The value -1073741382 is not of type UNSIGNED-BYTE.
- The test has been disabled on Darwin till the bug is fixed.

374: BIT-AND problem on ppc/darwin:
The BIT-AND test in bit-vector.impure-cload.lisp results in
fatal error encountered in SBCL pid 8356:
GC invariant lost, file "gc-common.c", line 605
on ppc/darwin. Test disabled for the duration.

+375: MISC.555
+ (compile nil '(lambda (p1)
+ (declare (optimize (speed 1) (safety 2) (debug 2) (space 0))
+ (type keyword p1))
+ (keywordp p1)))
+
+ fails on hairy type check in IR2.
+
+ 1. KEYWORDP is MAYBE-INLINE expanded (before TYPEP-like
+ transformation could eliminate it).
+
+ 2. From the only call of KEYWORDP the type of its argument is
+ derived to be KEYWORD.
+
+ 2. Type check for P1 is generated; it uses KEYWORDP to perform the
+ check, and so references the local function; from the KEYWORDP
+ argument type new CAST to KEYWORD is generated. The compiler
+ loops forever.
+
+377: Memory fault error reporting
+ On those architectures where :C-STACK-IS-CONTROL-STACK is in
+ *FEATURES*, we handle SIG_MEMORY_FAULT (SEGV or BUS) on an altstack,
+ so we cannot handle the signal directly (as in interrupt_handle_now())
+ in the case when the signal comes from some external agent (the user
+ using kill(1), or a fault in some foreign code, for instance). As
+ of sbcl-0.8.20.20, this is fixed by calling
+ arrange_return_to_lisp_function() to a new error-signalling
+ function, but as a result the error reporting is poor: we cannot
+ even tell the user at which address the fault occurred. We should
+ arrange such that arguments can be passed to the function called from
+ arrange_return_to_lisp_function(), but this looked hard to do in
+ general without suffering from memory leaks.
+
+378: floating-point exceptions not signalled on x86-64
+ Floating point traps are currently not enabled on the x86-64 port.
+ This is true for at least overflow detection (as tested in
+ float.pure.lisp) and divide-by-zero.
+
+379: TRACE :ENCAPSULATE NIL broken on ppc/darwin
+ See commented-out test-case in debug.impure.lisp.
