Subject: 30.0.50; starting js-mode or js-ts-mode eats ram until emacs gets 
 killed
Date: Sun, 12 Nov 2023 12:24:39 +0000

Running from the current master build of emacs when entering js-mode
emacs consumes ram until it is eventually killed by the OS including
when executed with -Q

Not sure how to get a stack trace as it has the process end without
crashing.

If you mean this recipe:

  emacs -Q
  M-x js-mode RET

then after it I cannot see any changes in the Emacs's memory
footprint.  It stays constant.  Do I need to do something else, like
visit a JS source file?

So the problem is only with js-ts-mode, not with js-mode?  Your
original report said both modes cause the problem.  js-mode doesn't
use the tree-sitter grammar.

Fine by me, but I'd like first to hear from you that js-mode is free
from the problem, otherwise the tree-sitter grammar is not necessarily
the cause.
