bug#53348: 27.2; Crash in mark_object

[Reingruber, Richard]

Hi Eli,

Thanks for looking at the issue!

The issue occurred today on another macbook which is x86_64 not arm64. OS and 
emacs versions are the same.

Yes, could be stack overflow. Is emacs' gc recursive? Will it crash if there is
a long enough list?

Sure. I will try to configure my environment for larger stacks.

Thanks, Richard.

    Looks like C stack overflow, or at least a possibility of it (you
    didn't show all of the backtrace levels, so it's hard to be sure).

    Can you configure your environment, or rebuild Emacs, so that the
    amount of stack space available to it is larger?
