The error is coming from exec_byte_code:
if (MAX_ALLOCA / word_size <= XFASTINT (maxdepth))
memory_full (SIZE_MAX);
It's more like a Lisp stack overflow than a memory exhausted situation
though, hardly calls for restarting Emacs. Perhaps the byte compiler
should refuse to compile such a large expression?
I can't reproduce in Emacs 26, but only because MAX_ALLOCA is bigger, I
think.
