Hello!

I'm using Emacs 27.x compiled from the master branch. I have noticed that after several hours of
work Emacs tends to crash or complete freeze the entire OS when I work on JavaScript code. I have
prettier-js which prettifies the source after saving the file to disk, but not sure if this could be
related. I also have suspicions on the parser of JS code, but because I have no idea how or where it
keeps the AST, I can't be sure if that is related to the crashes too, I come to notice that under
some circumstances –when the JSX code is fairly large and complex– Emacs slows down and feels heavy
sort-of-speak.

I would like to know if there is a way to monitor Emacs on a normal run and after it crashes get
back something that can help debugging whatever the issue happens to be. This behavior has become
recurrent during this month, IIRC.
