Sorry for following up again to myself, but I haven't lost the hope that
someone in the know chimes in at some point :-).
When I print the value that the window.eln compilation unit has in
objects_dumped
(lldb) expr -- $299->key_and_value
(Lisp_Object) $317 = 0x000000011004800d (struct Lisp_Vector *) $321 =
0x0000000110048008
(lldb) expr -- $321->contents [2*2010 + 1]
(Lisp_Object) $322 = 0xfffffffffffffffe (struct Lisp_Cons *) $324 =
0xfffffffffffffff8
(lldb) xdebug_print $321->contents [2*2010 + 1]
-1
We see (a) my lldb support has a bug (shit), and (b) that the value is
-1, which is DUMP_OBJECT_ON_NORMAL_QUEUE.
And when I go a frame up in the callstack, I see indeed
frame #5: 0x000000010014cc24
temacs`dump_drain_normal_queue(ctx=0x000000016fdfe300) at pdumper.c:3985:5 [opt]
3982 dump_drain_normal_queue (struct dump_context *ctx)
3983 {
3984 while (!dump_queue_empty_p (&ctx->dump_queue))
-> 3985 dump_object (ctx, dump_queue_dequeue (&ctx->dump_queue,
ctx->offset));
3986 }
Another frame up
frame #6: 0x000000010014b514
temacs`Fdump_emacs_portable(filename=<unavailable>,
track_referrers=<unavailable>) at pdumper.c:4175:7 [opt]
4172 {
4173 dump_drain_deferred_hash_tables (ctx);
4174 dump_drain_deferred_symbols (ctx);
-> 4175 dump_drain_normal_queue (ctx);
4176 }
So, I think what happens here is this:
Window.eln's compilation unit gets dumped normally the first time
around. But it also is put on the dump_context::dump_queue for some
reason. Add when the queue is processed, boom...
Hm again.
