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:

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.
