Also reproduced in emacs-24 branch (here and below, emacs-24 branch is assumed).

This looks a fundamental bug in eval_sub, probably introduced in r112828.
When compiling with --enable-checking, it gives:

../../emacs-24/src/eval.c:184: Emacs fatal error: assertion failed: pdl->kind == SPECPDL_BACKTRACE

In eval.c:

   2134        else if (XSUBR (fun)->max_args == MANY)
   2135          {
   2136            /* Pass a vector of evaluated arguments.  */
   2137            Lisp_Object *vals;
   2138            ptrdiff_t argnum = 0;
   2139            USE_SAFE_ALLOCA;
   2140
   2141            SAFE_ALLOCA_LISP (vals, XINT (numargs));
   2142
   2143            GCPRO3 (args_left, fun, fun);
   2144            gcpro3.var = vals;
   2145            gcpro3.nvars = 0;
   2146
   2147            while (!NILP (args_left))
   2148              {
   2149                vals[argnum++] = eval_sub (Fcar (args_left));
   2150                args_left = Fcdr (args_left);
   2151                gcpro3.nvars = argnum;
   2152              }
   2153
   2154            set_backtrace_args (specpdl_ptr - 1, vals);
   2155            set_backtrace_nargs (specpdl_ptr - 1, XINT (numargs));
   2156
   2157            val = (XSUBR (fun)->function.aMANY) (XINT (numargs), vals);
   2158            UNGCPRO;
   2159            SAFE_FREE ();
   2160          }

At 2141, if numargs is > 2047 (and so allocation size exceeds MAX_ALLOCA on
a 64-bit system), SAFE_ALLOCA_LISP pushes an entry of type SPECPDL_UNWIND to
specpdl stack.  At line 2154, set_backtrace_args modifies this entry assuming
SPECPDL_BACKTRACE.  Oops.

Michael, try this.  Stefan, please review.

I'm not thrilled at the idea of having to call backtrace_top every time,
instead of just using "specpdl_ptr - 1".  I'd much rather compute
specpdl_ptr - 1 before calling USE_SAFE_ALLOCA, for example.

BTW, don't we have the same problem for the subsequent call to
backtrace_debug_on_exit (and this one is worse because it is shared
among all the different kinds of calls, so we *really* don't want to
slow it down).

Hm...this simple fix:

causes bootstrap crash (with emacs-24).  Hard to explain why, huh?

IIUC this applies only to apply_lambda, where we call to backtrace_debug_on_exit
between SAFE_ALLOCA_LISP and SAFE_FREE.

The PDL stack is in a vector that gets resized (typically by
realloc+memcpy) occasionally.

Yes, I forgot about it :-(.

An issue should be fixed in emacs-24 branch, revision 117502.
