Is there an official MinGW (or other compiler) I should use to build Emacs
on Windows without issues ? mingw.org seems to have shut down and been
superseded by mingw-w64.org. (I'm usually a Linux user but I have to use
Windows at work, so I'm a bit less familiar with this ecosystem).

If you > still have this problem with the latest master branch, maybe try a > clean build. Ignore this. The real cause of this is that MinGW64 (which you are using to build) doesn't have getline in its runtime, so we now need to build the Gnulib getline module on MS-Windows if the system libraries don't have it (mingw.org's MinGW does have this function in its runtime). I've installed a fix, which should allow you to build the latest master, assuming you re-run autogen.sh and the configure script.

Great, thanks for testing.

The function getline comes from Gnulib, and the Makefile is supposed
to cause emacsclientw to be linked against ../lib/libgnu.a. If you
still have this problem with the latest master branch, maybe try a
clean build.

This is my first Emacs bug report, apologies if I'm doing something
incorrectly.
When I run 'counsel-ag and edit the text several times in a row quickly,
Emacs ends up hanging. This bug has the same symptoms as #52414, except
that one is reportedly fixed.
Here is a minimal (ish) .emacs file to reproduce the bug:
;;; -*- lexical-binding: t -*-
(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
(package-initialize)
(unless (package-installed-p 'use-package)
(package-install 'use-package))
(require 'use-package)
(setq use-package-always-ensure t)
;; Use Ivy for completion
(use-package ivy
:diminish
:init (ivy-mode 1)
)
;; Use counsel for better default functions with Ivy
(use-package counsel
:init (counsel-mode 1)
:bind (("C-x b" . counsel-ibuffer)
("C-M-j" . counsel-switch-buffer)
:map minibuffer-local-map
("C-r" . 'counsel-minibuffer-history)))
(global-set-key (kbd "C-c f") 'counsel-ag)
Here is the backtrace from the main thread:
