bug: Lazy makes neovim crash (using MSYS MinGW on Windows).

[ienapliss]

Did you check docs and existing issues?

• I have read all the lazy.nvim docs
• I have searched the existing issues of lazy.nvim
• I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

NVIM v0.9.5 Build type: Release LuaJIT 2.1.1707061634

Operating system/version

Windows 11

Describe the bug

I use neovim from MSYS2 MinGW. It always worked fine until some recent updates.
Using Lazy with MinGW packages will make neovim crash.
What's more puzzling: using the same version of neovim from the https://github.com/neovim/neovim/releases (nvim-win64.zip) works just fine...

Sometime I get some more information beside "Segmentation Fault":

  0 [main] git (17340) child_copy: cygheap read copy failed, 0x800000000..0x80000C500, done 0, windows pid 17340, Win32 error 299

599 [main] git 1909 C:\dev\msys64\usr\bin\git.exe: *** fatal error in forked process - couldn't create signal pipe, Win32 error 5

Steps To Reproduce

1. Install MSYS2 from www.msys2.org.
2. Launch mingw64.exe
3. Install nvim and dependencies
   pacman -S --needed git mingw-w64-x86_64-neovim
4. Use Lazy (use repro.lua below unchanged)
5. Launch nvim with: nvim -u repro.lua

Expected Behavior

No Seg Fault

Repro

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath, })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here

Closing this because apparently the issue is gone after updating the neovim package from mingw.

The upgrade did not solve the problem
