Re: emacs segfault on bootstrap

[Richard M. Stallman]

    A cursory inspection did not reveal any bugs in print_object.  Smells
    like a compiler bug.

    Program received signal SIGSEGV, Segmentation fault.
    0x0819c3be in print_object (obj=58, printcharfun=137788457, escapeflag=1)
        at print.c:2009
    2009          switch (XMISCTYPE (obj))
    (gdb) bt
    #0  0x0819c3be in print_object (obj=58, printcharfun=137788457, 
escapeflag=1)

    (gdb) p obj
    $5 = 137726760
    (gdb) xtype
    Lisp_Int

Do you think that frame 1 mistakenly treated an int
as a vector?

If so, could you look around some more and try to prove it
conclusively?  Try to determine which line did something wrong.
Perhaps you could then easily step through and prove that the
incorrect computation occurs in a certain line or range of lines.

That's all the info needed to make a useful GCC bug report
so that this will get fixed.
