sbcl-1.2.7 released

Dear all,

I've tagged and released sbcl-1.2.7; it should now be available for
download on Sourceforge, and binaries will accumulate in due course.
People might wish to exercise some caution: there was a late
freeze-busting change to the garbage collector, and testing at this time
of year is thin on the ground.  A brief changelog is appended to this
message.

Happy New Year,

Christophe

changes in sbcl-1.2.7 relative to sbcl-1.2.6:
  * optimization: returning constant values refers to preboxed constants
    more reliably. (lp#1398785)
  * enhancement: a STYLE-WARNING is produced if a compiler-macro is defined
    for a function after at least one ordinary (not inlined) call to that
    function was compiled, indicating a likely compilation order problem.
    Likewise a warning ensues if a call is compiled to a function
    that is subsequently proclaimed INLINE.
  * enhancement: always lose() when something goes wrong while saving a core
    (instead of just printing an error on stderr in some situations).
  * enhancement: frames in the debugger are now restartable by default.
  * bug fix: restore error handling on Windows x86.
  * bug fix: MAKE-SEQUENCE detects type errors in its :INITIAL-ELEMENT
    at compile-time when possible. (lp#330299)
  * bug fix: parsing of malformed type specifiers no longer results
    in a memory-fault-error.
  * bug fix: LOOP properly destructures nested lists in WITH.
  * bug fix: MACROEXPANDing the redefinition of an alien structure type no
    longer signals the wrong error.
  * bug fix: PROGV doesn't get confused by forced DEBUG 3 (lp#1405456).
