This patch allows the example to pass:

I have no knowledge of the exception handling implementation, so:
1. a proper root cause analysis would take me some time.
2. I have no idea whether the patch is actually correct. I'll try a bootstrap
and reg-test though, that'll gives us at least more information.

--- Comment #4 from vries at gcc dot gnu.org ---
The assert triggering is:
...
(gdb)
#5 0x00000000011325fe in redirect_eh_edge_1 (edge_in=0x7ffff64af4d0,
new_bb=0x7ffff64ae4e0, change_region=true) at src/gcc/tree-eh.c:2335
2335 gcc_assert (lookup_stmt_eh_lp (throw_stmt) == old_lp_nr);
...
Indeed the comparison fails:
...
(gdb) p old_lp_nr
$1 = 1
(gdb) p lookup_stmt_eh_lp (throw_stmt)
$2 = 0
...
And lookup_stmt_eh_lp (throw_stmt) is 0, because throw_stmt is NULL, which
presumably is not intended to be NULL here:
...
(gdb) p throw_stmt
$3 = (gimple) 0x0
...
throw_stmt is initialized here:
...
2334 throw_stmt = last_stmt (edge_in->src);
...
In fact edge_in->src is an empty bb:
...
(gdb) call debug_bb (edge_in->src)
;; basic block 15, loop depth 0, count 0, freq 0, maybe hot
;; prev block 14, next block 3, flags: (NEW)
;; pred: 14 (FALLTHRU)
;; succ: 7 (EH)
;; 3 (FALLTHRU)
...
Before pass_lower_vaarg, we have this definition in bb2 definining for _6:
...
;; basic block 2, loop depth 0, count 0, freq 0, maybe hot
;; prev block 0, next block 3, flags: (NEW, REACHABLE)
;; pred: ENTRY (FALLTHRU)

# USE = anything
# CLB = anything
_6 = VA_ARG (&cD.2333, 0B);
;; succ: 7 (EH)
;; 3 (FALLTHRU)
...
After pass_lower_vaarg, it's spread over several basic blocks:
...
;; basic block 2, loop depth 0, count 0, freq 0, maybe hot
;; prev block 0, next block 11, flags: (NEW, REACHABLE)
;; pred: ENTRY (FALLTHRU)

_32 = _30 + 8;

cD.2333.overflow_arg_areaD.7 = _32;

_6 = MEM[(intD.9 * * {ref-all})addr.1_21];
;; succ: 15 (FALLTHRU)

;; prev block 14, next block 3, flags: (NEW)
;; pred: 14 (FALLTHRU)
;; succ: 7 (EH)
;; 3 (FALLTHRU)
...
Before the expansion, the ifn_va_arg is the statement that could throw:
...
(gdb) call debug_bb_n (2)
;; basic block 2, loop depth 0, count 0, freq 0, maybe hot
;; prev block 0, next block 3, flags: (NEW, REACHABLE)
;; pred: ENTRY (FALLTHRU)
[LP 1] # .MEM_5 = VDEF <.MEM_4(D)>
# USE = anything
# CLB = anything
_6 = VA_ARG (&cD.2333, 0B);
;; succ: 7 (EH)
;; 3 (FALLTHRU)
$1 = (basic_block_def *) 0x7ffff64ae270
(gdb) call stmt_could_throw_p ( last_stmt ($1 ) )
$3 = true
...
But the last statement before bb15 cannot throw:
...
(gdb) call debug_bb_n (14)
;; basic block 14, loop depth 0, count 0, freq 0, maybe hot
;; prev block 13, next block 15, flags: (NEW)
;; pred: 12 (FALLTHRU)
;; 13 (FALLTHRU)
# .MEM_20 = PHI <.MEM_29(12), .MEM_33(13)>
# addr.1_21 = PHI <addr.1_26(12), addr.1_31(13)>
<L7>:
# VUSE <.MEM_20>
_6 = MEM[(intD.9 * * {ref-all})addr.1_21];
;; succ: 15 (FALLTHRU)
$4 = (basic_block_def *) 0x7ffff64aea90
(gdb) call stmt_could_throw_p ( last_stmt ($4 ) )
$5 = false
...
So it does not seem to be just a question of removing the last empty bb.

There's no exception connected to the whole va_arg sequence.
So the question is: should ifn_va_arg have ECF_NOTHROW?

Adding ECF_NOTHROW to ifn_va_arg also fixes the ICE.
And at gimplify_va_arg_expr, the VA_ARG_EXPR tree is non-throwing:
...

Yep, that's also the case with -fnon-call-exceptions:
...
(gdb) call debug_generic_expr (*expr_p)
VA_ARG_EXPR <c>
(gdb) call tree_could_throw_p (*expr_p )
$1 = false
(gdb) p flag_non_call_exceptions
$2 = 1
