--- Comment #2 from J-Donald Tournier <jdtournier at gmail dot com> --- (In reply to Richard Biener from comment #1) > Works for me with GCC 8.2.0 and tip of branch as well as GCC 9. It might > have been an intermittent failure but I only was able to check x86_64-linux. When you say 'tip of branch', are you referring to the latest snapshot of GCC 8.2.1? In which case I may rely this back to the MSYS2 project, hopefully they'll be able to release a working build relatively quickly.
