MSYS2 might have run into a related problem. Currently Emacs 28.2 cannot be 
built on the Github Actions CI with GCC 13.1 and native comp enabled because 
the build gets stuck during native compilation of files.el (all the other elisp 
files are compiled). I’ve attached a backtrace from the CI.

Meanwhile several people reported successfully building Emacs on their own 
machines from the same MSYS2 that runs in the CI. There’s a discussion on 
Github [1]. Downgrading to GCC 12.2 helps, and we’re still investigating the 
effects of various compiler switches.
