Re: emacs-current bootstrap fail on FreeBSD 6.2

[Richard Stallman]

    - the backtraces show that some kind of signal thingy happens at
      alloc.c:4244, but that line is just a function call and I can't see how it
      can fail.  Please keep an eye on this.  Try to see why it crashed at that
      point.

Various optimizations such as cross-jumping can confuse the line
number.  I think that inlining can also cause problems to be referred
to the wrong line.  Back when I worked on GCC, to debug a possible GCC
optimization bug once I knew which function was miscompiled, I would
just compare the .s output with the source.

I suggest testing with the latest GCC before going to so much trouble.
