(reported by Vsevolod Dyomkin) + * bug fix: sb-bsd-sockets has correct declaration of the canonname field of + addrinfo. (lp#1187041, patch by Jerry James) + * bug fix: uninitialized type-error conditions can now be printed. + (lp#1184586) + * bug fix: tests for sb-bsd-sockets no longer use a predefined port for + listening, allowing several tests to run in parallel. + * bug fix: during disassembly to *COMPILER-TRACE-OUTPUT* instruction + prefixes as used on x86 and x86-64 no longer sometimes print incorrectly. + (lp#1085729) + * bug fix: Specialised SIMD-PACK types can be negated. + * bug fix: Modular arithmetic is more robust. (incidentally fixes another bug + reported by Eric Marsden) + * bug fix: FP return values from foreign calls are always rounded to single + or double float precision on x87. + * bug fix: Known-safe vector access on x86oids should not fail spuriously + when the index is of the form (+ x constant-positive-integer). + * bug fix: Remove GPL-licensed files from source distribution. (lp#1185668) + * bug fix: backtrace printer no longer tries to create very large lists when + the arg-count register is clobberred by other code. (lp#1192929) + * bug fix: x86 should never signal an FP exception while boxing an FP value, + a situation that lands us into ldb. + +changes in sbcl-1.1.8 relative to sbcl-1.1.7: * notice: The implementation of MAP-ALLOCATED-OBJECTS (the heart of ROOM, plus a few SB-INTROSPECT functions) has been completely rewritten; it may now exhibit different bugs than before.
