[ruby-core:120731] [Ruby master Bug#21034] try to mark T_NONE object error after upgrading to 3.4.1

Issue #21034 has been updated by tenderlovemaking (Aaron Patterson).


These two lines make it seem like they are the same bug to me:

```
/usr/local/lib/libruby.so.3.4(gc_mark+0x16) [0x7f8e88955bae] gc/default/default.c:4456
/usr/local/lib/libruby.so.3.4(rb_gc_mark_vm_stack_values) gc/default/default.c:4436
```

@travisbell the backtrace from your corefile isn't enough to debug this. I can tell from this output:

```
#13 rb_gc_mark_vm_stack_values (n=62, values=0x7fac6ca72000) at gc.c:2291
        i = 29
```

that the 29th item (out of 62 items) in the VM stack has gone bad.  Each Ruby stack frame in your program will have pushed some number of items on the Ruby stack before calling the next function.  I can't tell from the gdb stack trace what functions push what, but it seems like maybe about halfway up your Ruby stack there's something wrong.

I think we can concentrate on #21021, but I'm not sure how much I can help without a core file or a repro program.

Hi everyone,

I noticed we started having some workers crash after upgrading to 3.4.1. I tried grabbing a core file and got this output. Is it enough to figure out what's going on? If not, I can reproduce this fairly easily, so I can grab more debug info if needed.
