This is a real stack overflow, so 1MB is evidently too low for Emacs.
(It could be that Emacs shouldn't crash in that case, but that's a
different bug, if you want to report it.)

Whenever you see ___chkstk_ms at the top of the backtrace, it's a
stack overflow.  That function is the one that checks for stack
overflow.

I think this "lower your stack" attempt is driving us from the real
problem, certainly with 1MB of stack.
